So lemme start this off from the beginning, first started tinkering around with my first car, a 1998 3.8L convert. pony. Love her, but sometimes I feel like the feeling isn't mutual. Put a cold air on it just cause, noticed a crack in the PCV hose, but being new to cars, didn't notice it. I went to school for engine performance and electrical systems since then so I have significantly more background. SO BACK TO IT, nothing happened. Then after a couple of races, it started to hesitate when I went WOT. Freaked me out, I put it in park and neutral, revved fine. Put it in gear, stumbled like no other. I got the car around 200,000 miles, all signs pointed to fuel filter. Replaced it. Problem continued. Figured okay it's time for fuel injector cleaner. Problem persisted. After hearing what happens with a stock MAF sensor and an aftermarket CAI, tried cleaning the MAF, still hesitates. To keep things short, spark plugs were replaced, wires and ignition coils too. Problem is still there, I will add, I replaced the hose to the PCV but the diameter was too big so my genius (sarcasm) self tried to seal up the gap with tape. Help. People keep asking to race and they're growing impatient.
