Got a issue with my 96 gt. what's happening is as soon as I start up it runs fine for about a min or 2 and then if I get it to much throttle it sputters but if i back of the throttle and just ease into it slowly it won't sputter or miss. I changed plugs and no difference. I'm thinking it has something to do with a sensor just not sure which one. I'm throwing a purge valve code and misfire codes 7 and 2.
Did coil packs and plugs 2 weeks ago. Just odd that I can ease into throttle with now miss up to 5k but if I give it just a little to much I misses/stutters but mainly under load
Do you still have cats on your exhaust? (Plugged up?) could be o2 sensor also.. I had this issue with my 4.6, and then I changed out exhaust, went cat-less and done an rear o2 delete, with help of my sct tuner, I turned off my rear o2's, and cleared my codes, and they haven't popped back up.. One code can throw a few codes.. For example; bad plug (misfire) may also throw code for air/fuel mixture, and throw codes for o2's.. All because of a plug..
Woooot!!!!!
