GTP Running Rough.. few new parts but still not running right.. HELP

[azmattaz06]

Ok so i changed my plugs about 5,000 miles ago or less so they're not too bad..i just recently did the Wires and I've also done the fuel pump and fuel filters.. What next? i herd i should be using the NGK plugs is that true? if not maybe i should run it thru the injector cleaner machine..? anyone have anyone other clues besides what i wrote down? thanks

Quantify "still not running right." At idle, going down the road, hard starting, no boost?

did you gap the plugs before you put them in?

 

[azmattaz06]

yes im gapped the plugs.. and by not running right i mean running rough kinda feels like maybe a miss or something like that.. after all that i'd expect better gas milege also it's getting about 22mpg..

Again...what do you define as not running right? Is it not boosting? Is there a vacuum leak? What? Has it thrown any SES lights? Try and help us out man, a misfire sounds like you didn't get the wires on right or something since you just changed them or your coil packs might be bad. Anyway you can get a video of it?

Well first off it was running the same before the new plugs so thats not it. And im not sure how to explain it it's boosting fine but when it's at idle it's not just a smooth running engine it' kinda missing and not like a good running engine should sound..

did you check the vacuum line running to the map sensor cause thats the one the works the boost gauge. as far as the misfire try cleaning the mass air flow sensor cause i had that problem and found some dirt on it and that helped and it didnt give me a code so u can try that one.
