i changed the #6-3 coil pack, EGR valve,Mass air flow sensor,wires,plugs,fuel filter,neg cable,o2sensor,ok if i run car for about 1-1/2 still shutit off and try to start it after about 20mins it will start but still putter and stumble idle is a little rough. Ok could this be the TPS or the IAC? its a 94 Bonnie not super charged The reason i changed the MAF sensor I was always told if you unplug it and car stays running its bad. So after 300.00 for the EGR valve MAf sensor and other stuff and a huge headache Im gonna sell it for a penny. I need this car as no money to get a new one and cant afford to have car in garage I do all work myself. in previous post I stated car was coded and had these codes
1-EGR pintel postion sensor
2-Tourque (not sure forgt)
3-Cruise control
had a few stored but cleared them and they are gone so far.
well any help would be greatly accepted and I do appriciate it greatly.
Thanks
Michele
