Sup guys,
Well over the past few weeks I've noticed some ignition issues at idle and some hesitation and "back pressure like" missfiring while driving but off the throttle.
It has gradually gotten worse and worse to where we replaced the spark plugs with 2 step cooler iridiums (remember my car's boosted) and hoped that'd fix the problem... Well it didn't and so I pulled my CEL codes and of course saw the first two and expected them (the VTCS code from the ECU swap and the Mil fix code, both of which I'll take care of tomorrow) but then came up the #300 code indicating a random missfire.
So the next step was to replace the coils... Did that... And same thing- only now it's gotten so bad to where I'll stall at every red light or stop sign. Basically anytime I drop under 1K... This makes for a pretty tough ride to work everyday.(headshake
So today I went and got the Magnecore 8.5 wires in hopes since it being the final piece of the iginition puzzle that it'd be the answer to my problems... But it wasn't. Instsalled them at the shop I got them at and stalled all the way home.
I'm starting to get frustrated becuase I feel like I've run out of options. I'm confident it's not a vacuum leak becuase I've traced all my vacuum lines and have tested them for holes, leaks, or rips. Same goes for the intercooler pipes and BOV hoses.
I've read on another thread that it could be the EGR valve gone bad but if that were the case I should've gotten an EGR CEL, correct?
Any advice would be great guys because I feel I'm at a dead end.(scratch)
