lately when i'm idleing at a stop light for over 4 mins and i start to go the pedal doesnt do anything and it drops down to 200-300rpms and i'll be flooring it and it wont go anywhere then it just dies and it takes a few mins to start back up?? no engine lights or codes... any advice would be appreciated thanks

ok it just did it to me 3 times!!! and when i give it gas and floor it to try to go it pops a few times then dies???? could it be a bad o2 sensor or a clogged cat? i recentley put stock manifolds and cats back on.

 

when are you going to bring it by so I can log it? That is really the only way to find out what is wrong with it... Sounds like a bad O2 sensor IMO...

 

i can bring it by pretty much anytime your off work. maybe its detonation since i've only been putting 87 in it?

 

Friday will work, around 4:30ish, unless my headers are ready then it will be a bit later...

 

If your pushin the gas to the floor and the motor isn't reving when its hot then its probably the cat converter... Easy way to check is to remove both front o2 sensors and try reving it up...
