my ss hesitates !! HELP

[Lawdog]

I do believe sir that if you put the car in sport mode on the gearshift lever the afm is turned off and it stays in 8 cylinders, check that out if so then there should be no problem if what he is saying is your 4-8 situation, but if it still does it then you have a different prob.
and yes it takes awhile for the computer to relearn after you put the stock cleaner back on. It doesnt happen right away.

Davedog did you ever get the problem resolved??

Just an idea, but if you haven't been using 91 octane in your SS then this could cause the issue. The car can still run on 87 octane, but the performance will be a bit more sluggish. Also if you start using 87 octane the computer recognizes it and will have to go through a learning curve.

Actually, if you EVER put 87 octane in the computer adjusts down to the lower octane table and NEVER relearns to the higher 90+ octane table. The only way to get back to the higher octane table is with a fuse pull. There is a sticky thread about it over on camaro5.com. I don't know that this will help this situation though.

Hi guys ! Car went in again yesterday they say it's The muffler so they r putting a new one on.I know it is not and if the car still does it then I'm going to ask to test drive one they have on the lot and see if it's the same (I don't think it is).
So I will let you know when it is done and thanks for all the help .

Ps I only use shell 93 gas

This could be part of your issue as well, Shell gas sucks!!!! Try switching to BP because they have much better fuel. Talk to most most speed/tuner shops and I am sure they will agree.

Do you have an Auto? All Autos are like that .. I went with Vector Motorsports Mail Tune and they also tune your CAI also. It was like day and nite.. The tune was simple and fast .. there are 2 parts one for the Tranny and one for the Engine..I downloaded both.. NO hesitatation at all and tires chip when shifting when getting on it.This is the way Chevy should have done it stock. I know you don't want to void your warranty, I was in the same boat.. Glad I did though. You can download your stock tune back in fast if you take to the dealer .. they say the Dealer can't tell but who knows.
