this is going to be a long read so prepare yourself; i want to give you guys every single detail so maybe you guys can tell me WTF is wrong. stupid car... well, one night i was driving and then my car started sputtering and would cut out(decelerate) for 1-2 second then come back again, and it would keep doing this constantly. so my friends and i thought it was the dizzy, so i changed to all new ignitor, coil, and spark plug wires. sweet, it went away. now a month later, it started doing the exact same thing, not knowing what to do, and completely confused.. somebody suggested that it was the iacv and disconnected it and said if it is doing those things(bogging/sputtering) its normal with it disconnected but its not suppose to do that with the iacv connected(supposedly meaning, the iacv is doing its job), but i have use to drive on disconnected iacv and it was fine, just had a low idle and threw a code. but i changed the iacv anyways and it went away, i don't know if i really solved the problem.. this has been a waste of time and money. i never get a cel btw. i'm thinking why would changing the dizzy internals that one night solve the problem when it was the iacv to begin with... help me think, because i'm just completely lost and confused. could it be something on my bbk 70mm tb?

I recommend inspecting your TPS sensor. A sensor that is out of calibration will generate the same kinds of symptoms. Although this does not explain the intermittent occurrence of your problem.

Hmmmmm......

 

yeah i did think of it being my tps but that makes no sense how the problem would come and go like this and not just do it all the time.

 

vacuum leak? fast idle valve if it has any.

 

if it was a vaccum leak, wouldn't my idle constantly surge? my idle only surges sometimes.

bump

 

weather conditions?
