running rich at idle will idle pretty low. is it doing that?

if it rev's high then loses rpms... it's prolly the fast idle thermo valve... or it could be the idle air control valve. check those.

i doubt its either. he has diff issues

[Vuongy_Dong]

also, did you mess with the tps or replaced it recently?

[sullen]

sounds like tps.

might be a bad MAP sensor.

[SLow_POke]

might be a bad MAP sensor.

BINGO


. you say you been running like this for about 2 years
? or did i understand wrong?

[iEvo]

yea check the map sensor. if its bad then it could be tellin ur ECU that ur under a load when ur not and it will just keep dumping fuel

[ryan34]

thanks 4 input replaced map sensor already, car ran good when i had it running then popd the head gasket had it rebuilt cuz i let it sit got the motor back put it in and its running super rich cant drive it nowhere cuz it smokes so bad still the same replaced filter map sensor dont understand cuz it ran good b4 i took the motor out could it be a cut wire ( is there a wire that would make this problem)
