Had a quick question about choking on deceleration.
 

I think I fixed the smoking issue(for the most part and did a few other things for this season)..BUT

I have always had this issue:....Upon releasing the gas pedel and allowing the car to slow itself by the gear with no brake on..and after a bit of deceleration at high rpm's its starts to choke on itself and sputter..all this goes away with a minimal amount of gas pedal.


Any ideas??

TB plates or IAC sticking.

Actually I dont think the IAC functions correctly...a whileago we disconnected it and nothing happenend!...hmmmm

Choking? What does at mean? Shutting off? Does it happen at a particular mph?

Re: Had a quick question about choking on deceleration.
 

Choking like it cant breath or not getting gas maybe.

not sure of mph...its usually after about 3-5 seconds of deceleration

If you unplug the IAC while the engine's running, it will hold its setting which might seem like nothing happened, at least for a short while.

OK Hib, pull it while its running and leave it off longer?

before when I had a smoke issue, the idle would fluctuate, currently is rock steady at 950 rpm.I thought that was a indication of a nad IAC.

What was the smoke issue?

Re: Had a quick question about choking on deceleration.
 

What mods on the motor to have a 950rpm idle?

Re: Had a quick question about choking on deceleration.
 

If you have a GM EPROM (?) then the program has DFCO, it's a fuel cut off under compression braking. Could this be what you are feeling? I forget at what rpm it comes "in", but it's closer to idle speed than not, say about 1100 or maybe less....I don't notice it any longer as I guess I'm used to it now. When I first got the car I noticed it right away. Just a thought.:o
