2001 MP3 turbo with:
-garrett super60 turbo
-vortex fmu
-sard bov
-fmic
-p5 ecm
-manual boost controller (boost has not seen over 7 psi since i got it)
-aem wideband
-engine and trans with about 65,000 miles
(all work done by previous owner)
On my way home from work a few weeks ago my car just started to sputter really bad like it was running on maybe 2 cylinders. its never done that before so I just drove it about half a mile further home.
The next day I run some seafoam through the tank and it doesnty really help. I take it around the block and it sputters worse and worse until it finally dies and I have to push it home. It would just start and just die within 1 second after that.
I pull my plug wires off and on the two cylinders with the coils on them the spark plugs are loose enough to move around with my finger so I pulled them out and they are completely BLACK. I pull the other 2 out and they are the exact same way, black with like sut covering the porcelain.
Changed the plugs with some new ngks and now it will start and idle BUT when I give it some gas it just stumbles and the rpms barely go anywhere. Sometimes when I give it a little gas I'll hear a squeek sort of like a belt (the same sound I hear sometimes when I first start the car or flip on the heater in the cold or the ac) and other times like a clunk.
The only code I have as of now is p0300 which is random misfire. Before I cleared the codes p0302 popped up but not anymore.
Just looking to get some insight before I further research it. This is the first major problem i've had in about 3 years with this car so hopefully its nothing big.
So far from what I've looked up it could possibly be:
-maf
-coils
-something else ignition related
Please help and dont worry, I have been using the search function all day
