Hey guys whats up. My 02 GT has been tugging on me for a lil while, it happens when i either hold the gas pedal steady and sometimes when i give it some gas. I changed my ignition coils, and plugs, changed fuel filter and fuel pump. I know that i need to get my car re-tuned due to the fact i replaced my fuel pump and headers. Plus before i changed my fuel filter and pump my fuel pressure was at 29psi which is low, but now it reads 50 psi which is a big difference. This problem is driving me crazy can anyone give me some advice!!!!!

 

sounds like a miss... but it seems like you got everything covered....is it tugging like a misfire or is it maybe your clutch slipping?

 

its tugging like miss, I have changed my spark plugs with Bosch platnum 2 plugs and a guy at a car show told me that for some odd reason our 4.6 does not like those so im going to take them out today and look at them. But i really dont think that thats the problem.

 

it might be a bad oxygen sensor. one of mine is bad right now and it's causing a miss while cruising.

 

I fixed it thank god!!!!!!!!!!!!!!!!!!!!!! It was a loose spark plug. I couldnt believe it, I removed the ignition coil and then right when i put the socket on the sparkplug it was in there but loose, i could turn with just my hand on the etension. Boy did I get lucky, after I hooked everything up I started the car up and it was so smooth. [sm=bounceybounce.gif]
