Thread: GTP sputtering, misfireing under load

Cam sensor change, but didn't solve the problem.. Didn't have enough for the plugs.. Hopefully it will get me through the week...

Thank you so much! plz do keep me posted. I didn't even know about the sensor relearn.. How whole I do it ? I replaced both sensors just cause I found on the 3.8 they piggy back on each other so one can fault the other. Plus I found a video when pulling the belt and the water pump pully I found them pretty easy to replace..
So after that didn't solve the problem I switched the coil packs to see if the problem moved. I scanned again. Same misfire..
So I got a few bucks and replaced #1 plug and wire! Seemed to have smoothed it out.. Going to get it scanned again and see. Will keep ya posted..
I did find that I think the valve cover gasket has a lot of oil sweat on the bottom side.. The plug when I pulled it was covered with dirt and oil?? So I gave the valve cover a little tighten.. Thinking I may do that replace real soon. And the rest of the plugs. They look like the original wires, numbered and all..
So well se how it does. Plz keep me posted as well

Do the plugs look worn? Whats the gap?

They looked pretty bad. A bit of oil on them? Kinda wierd. But the new thing that happen today was it wouldn't start, I had to give it gas and keep gas pedal down to keep it running. Down the road it drove great!! As soon as I stopped.. Died... Then repeat..

Try cleaning the MAF with the approved cleaner and see what that gets you. A gunked up MAF or IAC could cause this. Might be time to remove the TB and clean it as well. You def. need to get some plugs and wires on it soon.

Ok new issue, I beleave its related.. The cars been running ok for a little bit. I'm driving down the road and the car hesatates like its going to die again... But dosnt , in stead the tac dies.. For looking in to it it sounds to be close to crank shaft sensor. Now I replaced the cam shaft sensor because that's the code I had. But looking at the wires. I'm guessing the crank shaft sensor could throw this code as well. What ya guys think. You think that's it?
