i was wondering if anyone knows whats wrong with my car. some times it boggs while im driving like if i give it more gas it just putters. i dont know. i think it might be my o2 because when i floor it it runs normal. but when i ease off the gas it starts studdering again. since i guess the ecu stops running of the o2 after 80% throttle. but i dont know. if anyone could help me. id really appreciate it. oh and my car isnt boosted either. well atleast not yet.

 

If the car is bogging on you...Bog it back :P

 

Sorry I was post whoring.
Yah it could be your O2 do a test...put a voltmeter inbetween to check the voltage and let someone play with the throttle. I don't know the exact volt reading...searhc on the net

 

also check MAP sensor. make sure lines are tight, if u have a spare handy throw it on there.

 

i just all of a sudden happened. i didnt even touch anything. i took out my o2 sensor. and it had a big white spot on it. i cleaned it off with some wd40 and drove it around for a while and took it on the highway and it didnt do anything so im assuming it might be that. but i dont know we'll see
