i swear to god, its like once a week its somthing else !
 

alright this is whats happening, im having a real air fuel ratio problem .... my car not all the time but every once and while (more the i would like) starts running like really fat.

when i stand on it it runs like crap popin through the exhuast and hesitating like crazy ,only at low RPM's though , i hit 3 grand , and BAM !! SHES SCREAMIN With power, its kinda feels like the power comes on like a toggle switch.

it doesnt run like this all the time, which makes me thing its sensor related, i changed my o2's and my coolant temp sensor. didnt change my MAF yet .... any ideas guys ? thanks

Do you have an a/f guage? Sounds like it could also be ignition/timing related. Maybe a wire grounding out or something.

accually, a few days ago, the car was running really fat ! i was setting my timming (i set it to 14degrees) after putting the chip back in , i noticed when i rev the engine and the timming didnt move with the revs, and the chip was still in ??!!! so u took the chip out on the out and took a peek inside at the conectors and noticed they looked all corroded so i figures it was getting a bad conection, so i put a male and female conect setup on the 2 wires, so u when i check the timming now , i just pull the conections off ...

after that the car ran good (for like a day) then it was back to the same crap, runing rich durring low RPM's .....
