would like to say hey to everyone and that this site kicks ***!

i have a problem with my car idleing. normal driving its fine but if i floor it and then when i let off it becomes real stumbely and shake, sometimes stalls. since this started happening the car seems like it has lost some power. i have been told either knock sensor tps or iac checked for trouble codes and there are none

thanks

 

may be a fuel pressure problem, fuel pump may be messing up a little.

 

could be..............it had 2 trouble codes when i got it, one for maf and 1 for esc, the maf connector was a little loose so solved that but the esc trouble code just vanished 1 day

 

anyone else have suggestions

 

vacuum leaks and dirty fuel logs and injectors
