I need Guru help!
I was driving home from testing Wednesday night. I made some good clean passes in preparation for some races Friday night. On the drive home the car started bucking,missing,and backfiring, at part throttle acceleration, especially when the converter locked.If you gave it throttle it cleared up. I parked it till Friday night. I went over to my shop Friday night.I changed my alternator because I got a new high amp one. I changed the cap on my cam sensor, because the old on had a crack and I thought that was the reason for the missing. Now the car won't really fire and run. It cranks, but it sputters and backfires. It only tries to fire when you give it gas but it just pops and bangs. Today I changed: the cam sensor cap,coil pack and module,chip,ECM,crank sensor. I looked at the TPS[.44v],battery[12.2v],coolant temp[93F],IAT[93F]. I checked all my grounds. I'm really at a loss now. The car was idling perfect when I shut it off on Wednesday. I didn't try to start it before I changed the alternator and cam sensor cap. I know I'm probably missing something simple. I'm open to any suggestions!!
