Maybe. But I haven't had any temp related issues. Temp, fans, thermostat, works fine even had the system flushed when I bought it. The air pump valve is directly related to cold starts that's why I've been leaning towards that. But could be wrong. I saw someone test coil packs by slightly moving the...

So P0301 and 302 have come back separately at different times in the last few months. I again went and redid my spark plug job ensuring everything was to spec and cleaned throughly. I'm just kinda lost. The car has 0 symptoms when it's at temperature or even slightly warm. But the first start of the...

I went and redid the job. It seems like whatever coating that came on the spark plugs just messed them up. Took them all out and cleaned the crap off and what I could in get to in the motor. Put them all back and it was fine again. No codes still atm.

Started over in my thinking and ditched my ngk plugs I put in at the beginning and went to oem bosch platinum ones. But now my idle is fluctuating like badly wanting to stall. One of the plugs bad maybe?

I had a mobile mechanic friend of mine look it over a few times since ive had it and try all the 5 or 6 different scanners he had but no avail other than the same generic ones I got. He recommended doing the cam and crank sensors. Im just hesitant with sensor replacement after the several I replaced...

How does that work? I understand the terminology. But I'm a little lost. Is there joke going over my head? Lol

Good idea. When I looked at a diagram to just make sure what order they went in it also had the firing order listed. Cylinder 1 is first of course. So it occured to me, could this be a explanation to starting rough for 5 seconds and no other noticeable symptoms? I'm just trying to think out loud if ...

This is nuts! The CEL came back after clearing the p0300 again and for the first time it's given me a cylinder p0301! It has new spark plugs so I'll start by heading back to the pick n pull and grab a few coil packs and maybe some injectors if I can. I mean should I be looking at anything else?

Could a oil leak on my injectors be causing it? I replaced my filler cap and gasket but it still leaks from the base of it. Which alot of it does fall onto them

I previously took it to the best euro specialist in town and they did their own testing including and smoke test and couldn't find any issues. I hesitately did the whole pcv replacement while they had it. Which left me initially with that p1655 code. They even told me the condition of the system was...
