What spark plugs are you using? Is the gap correct? What codes are being thrown? Have you looked at the coil pack wiring harness?
Autolite Platinum plugs... the gap was set for whatever AllData told me to set it at... (I cant remember what that was off the top of my head)What spark plugs are you using? Is the gap correct? What codes are being thrown? Have you looked at the coil pack wiring harness?
Currently not getting any codes, and no I havent... is there a valve on the fuel rail to hook up a pressure ga. ? if so, what is the pressure supposed to be?Please post any and all codes you currently getting; have you tested the fuel pressure yet?
I've heard this, but could the brand of plug really make it run the way it does in the vid??I would maybe try running some NGK or Bosch plugs. VWs can be a bit picky on spark plug brands.
it has 131k, (It wasn't sitting for a year until it did this... then I parked it when I couldn't get it fixed, now that I've forgotten all the frustration, I am wanting to give it another try before sending it to the junkyard)How many miles does it have? You could look at the throttle body and if its dirty, clean it and try cleaning the MAF sensor. I'm not for sure but I bet it would help if its been sitting for a year
I'll drain it before messing with it now, all this info is from before it was parked. (including the video)Are you still running the year-old fuel?
OK, I will definitely try these things, the MAF & throttle body... now, my question is, IF they needed cleaning, and that was the cause of it running bad, wouldn't the new plugs NOT make it run smooth for a short period of time? - or.... are those being dirty causing it to foul the plugs, hence making it run bad?I would clean my throttle body, clean the MAF sensor, put fresh premium fuel in it, and put some injector cleaner in the tank and let it idle for a while. I was reading something not to long ago about misfires and they put some fuel injector cleaner in it and it fixed the problem.
I'm not sure, but if it were my car, that's what I would do since it would cost like only cost around $25. You can try seafoam too, I hear that it does wonders. Look up on youtube detailed Seafoam treatment vw jetta 1.8I'll drain it before messing with it now, all this info is from before it was parked. (including the video)
