ok here are the symtoms: stumbling, no power, hard starts, bad engine noise
what happened: put a new timing belt on, tensioner wasnt quite right, belt came loose and slipped a tooth of timing. got it to the shop today and the timing is all reset and great - car is running nice. that was at 2pm drove home everything is fine. left my house at 4pm to go to work car is fine. . . gradually starts to stumble a little - step on the gas alittle and it sort of bogs down - drives fine at minimum throttle. . . as the 15 minute trip goes on cars starts stumbling really bad, no power at all started having some engine noise (clanking) - rechecked timing. . . . still in order with good tension on the belt.
what I did before i left for work: plugged my datalogger and saw that all 3 fuel trims were lean - low at 139.8% med at 102% and high at 107% - turned up the fuel on my afc 10 minutes later it all goes down hill
could this be: fouled plugs? failing coilpack?my car is a pita pos?
