  1. The transmission problems continue... Last week I pulled the Sam unit, inspected it, and found some fractured solder points. Pulled the old solder off, and resoldered with some lead based solder. Car ran fine for a while, but every once in a while I have the transmission actuator act up on startup (clicking, binding, etc.). I shut the car off, let it sit for about a minute, go to restart and it's typically fine afterwards. This is happening about 1/10 times I start the car, and always happens when I shut the car off, then go to restart half an hour to an hour afterwards. Almost always happens in wet conditions too. From what I've researched I have come to the conclusion that the next step to take is inspection of the transmission wiring harness. I don't know how to test resistance or electrical flow on the wires, however I can pull the harness and inspect ever inch of wiring for breaks/corrosion/fraying/etc. How difficult is it to access all the plugs and pull the harness up for inspection? Are there any components that need to be removed to gain access? I had seen on the rpm sensor, there is a metal clip locking the plug in place, that I am unable to access, should I just pull the whole sensor when removing the harness? Going to tackle this on the weekend, but just need a bit of guidance on how to get the harness up to a point that I can inspect as much as possible, seems the air deflector for the intercooler is quite in the way of a couple plugs as well, does that remove quite easily much like the alternator belt guard? Thanks
  2. Thanks! It actually turned out better than I thought it would. Rims were a bit pitted and looked like crap when I bought the car and so I decided to paint them something to really make it stand out until I eventually get some alloys that actually look good on the car. Always liked the purple/gold color combo and worked well with the little smart
  3. Haven't done much to the car recently but I did just recieved my S-mann scoop, painted it up and got it installed. Looks really good on the car, definitely a more sporty look for sure!
  4. 450 petrol models and the roadster do have 6 sparkplugs, which I do find odd in a 3 cylinder car lol.
  5. No clue what the speakers are mounted in. My car is the 2006 pure model, so I assume it's just the crappy 4" speakers, which honestly is a massive improvement over the JBL clip Bluetooth speaker I was using lol. I do plan on upgrading to the bass boxes with the 5" speaker setup eventually, but it's a want and not a need so it'll have to wait. And I'll definitely look into wiring the power supply to its own seperate source, all I did was just wire the new deck into the factory harness and figured it's good enough for now, I don't listen to music super loud anyhow and I do typically prefer driving with the radio off so I don't use the radio much as is.
  6. Finally got around to installing a radio in the car today. Got a Kenwood kdc-x300 deck installed. Owned the car since April this year and finally got tired of no music so it had to be done lol. Super simple and straightforward process, just hardwired in the harness for the aftermarket deck. Tried switching constant and switched wires at first as that's what I've read 99% of the time, radio worked, shut off the car, turned it back on and settings were reset. Then put constant to constant and switched to switched, and the stereo works perfect, settings stay as they should. Speakers are far better than I expected too! I do want to upgrade eventually but they'll do just fine for the time being!
  7. That's the plan for when the new nozzles come in. Placing the nozzleless injector body's and associated components in for another hour long soak. Will definitely do a little vid on the old vs new spray pattern, I'm actually really curious to see the difference as well tbh, but totally willing to share on the forum here. Bonus to doing the pre cleaning the last couple days is that the injectors will just slide right out when removing them again which will be nice! Lol Thanks again for the input and advice, super appreciated as I learn working on these little cars.
  8. Injectors are all pretty clean after a couple cycles in the ultrasonic cleaner! Ended up just using silver anti-seize and got everything all put back together. List one of the retainer clips for the return line, so made a trip to Richmond Mercedes, those things are as valuable as gold.... $7.24 before taxes each. Car runs far better than it did, acceleration has a ton more pep, idle is nice and smooth. Looking forward to seeing how this has impacted fuel economy too and can't wait for those new nozzles to come in.
  9. Damn it cylinder #1!!! Why can't you be like the others... 🙄. Also, sudden realization here... There was 2 f**ken copper seals in this injector port! No wonder this injector was beyond stuck in the engine. This bugger is beyond stuck in there, gonna get a long M8 bolt as I've seen on some YouTube vids or try the flat screwdriver trick when I can go buy one tomorrow, not willing to pay much for a tool to remove one seal. But damn, looking at the previous photo I knew that bloody washer came off with this injector. What kind of mechanic worked on this vehicle previous to me?!? Other 2 ports are nice and clean, ready for injector install, just need to wait until tomorrow when I can get something to get this seal out and clean this port all nice and shiny like the others
  10. Just doing a soak in solution in the ultrasonic cleaner for now. Will deal with taking the caps off and doing a far better clean when the nozzles come in this Thursday (according to Amazon). Actually using spray nine grez-off mixed 50/50 with hot water, ultrasonic temp at 55°, and it is just destroying the carbon. Gave the rusty injected a light sand on the body to get rid of rust using 300 grit sand paper, it actually wasn't near as bad as it looked dirty, but definitely not as good as the other 2 injectors which came out fine. And yeah, I'll run over to Canadian Tire and pick up a little vacuum, somehow make a nozzle that I can attach tubing to and get inside the cylinder to suck up anything that fell in, because, alot fell in on cylinder 1. I just watched it crumble and fall into the hole, I was like, noooooooooo!!! 😅. Thanks again for the input Willys, super appreciated. Pic is the super rusty injector shown earlier, cleaned up quite well after a quick sand!
  11. So, uh, what would be the best method for cleaning out the cylinder? Cleaning out the injectors today, and holy crap are they filthy. Injector #1 gave me the hardest time, it was rusted in, so I've gotta do a heavy clean on it (can't wait for the new nozzles to come in). Other 2 injectors came out pretty easy, #3 being the cleanest and #2 wasn't horrible. But yeah, ended up having to use a pry bar and vice grips to break it loose, and found the crap in the picture (some already fell into the cylinder). Should I just use a vacuum with a hose narrow enough to get in the cylinder bore to get out as much as possible? Any advice is super helpful, as this is my only car, and it needs to run by Sunday at the latest (crappy tire is a 5 minute walk away, so I can get whatever necessary to get this dealt with).
  12. Oh, had no clue, went of what everyone says is a reputable source for info on these cars. At least I know for next time now
  13. Was at 33ft/lbs (45NM) as per instructions on evilutions website. Didn't even get close to that torque before it snapped lol. That belt did look pretty good but one day I was under the car and saw the split as the belt was on the crankshaft pulley, belt looked kind of glazed on the ribs so decided to swap it out with a belt I've had in my toolbox for about 3 months now, been meaning to get around to it but seeing that crack made me get to it asap
  14. Got the belt change out today, previous one was cracked and really worn. Older cars are sooooo fun to work on, especially when bolts snap...😒. Ended up just using a ratchets and prayed the alternator to where it was sitting before, can twist the belt a quarter turn with decent force so figure it should do until I get a new bolt for the alternator and set the belt proper..
  15. Yeah, it was the little white plug in the front of the battery inside the battery well. When I took it apart even further to see how bad it really was I could definitely see some burning on the connections and surrounding plastic from it arcing due to corrosion, good thing I caught it when I did. Good to know about what some of the functions it controls, wasn't having any issues pertaining to those but maybe it was causing issues for the SAM unit itself. Hopefully it is the issue that was causing the electrical faults I was having, so far so good, but its been less than 24 hours since the repair and I gotta give it a week or so to see if it really did resolve the issue. And yeah, the foxwell unit is great! Only downfall I have with it is that when I go to the abs diagnostics section, and go through the options to locate my car model, it only give the 450 up to the year 2005 so I can't select my actual model of smart. but overall it's a great little unit, done well for me pertaining to OBD2 stuff. Not sure what the difference is between elite and plus models, but it works for what I need it to do.
