I done a tune up but now the cars still runs but hesitates and when I give it gas it also acts like it is not getting enough fuel but will not quit. Seems like a spark plug is bad but have replaced them all with NGK. Like I was saying it runs and drives, does not quit but atcs like it is not getting enough gas, can anyone tell me what to check?
Thanks

Injectirs, guel filters, fuel pump, throttle relearn procedures.

 

my guess is a vacuum leak somewhere

 

Air filter, MAF, TB relearn, vacuum lines, plenum, fuel lines, fuel injectors...start troubleshooting
