Needing help on my 07 SS/SC. Im new to the forum. The engine has been stuttering at idle especially after i drive it for a while. there are times where it stutters bad enough to where the whole car shakes. I checked the TPS and spark plugs. Nothing in my eye came to a solution. I took it to chevy but they said everything was fine. Could anyone help me on the problem or let me know what else i can do. I also have changed my fuel from 87 to 89. I havent added any mods to it either.

 

run premium only, and take it back to the dealer for a reflash

 

I didnt think ss/sc's take too kindly to 87...did it burn off the whole tank of 87 yet?

 

depends how you drive it. if you drive like an old man and NEVER see boost, it won't be bad. but if you ever see boost, even a little bit, you'll probably get gas mileage so bad that it doesn't make sense to save the 2dollars for premium. not to mention no power.

 

I have filled a couple of times since my last full 87 tank its been 2 months already. I drive like an old man when im short on cash and have to make the tank last me another day or two. but other than that im usually boostin around 5 and 12 on the weekends at the races.

 

i bet your'e getting worse gas mileage than you would on 93, which means you're spending just as much money to drive x amount of gallons, but with less power. i woudl stick with 91 or 93.

 

sorry but you shouldn't own a ss/sc or a 2.4

 

why are you running with 87....... god damn it

93 plz and run some injector cleaner through your next tank to get it all out

 

put some octane booster in there if you still have some in ur tank or add like 94 or something to bring it up a bit and yes add some injector cleaner

 

So 93 it is then. but if that doesnt work im trading in for the new SS/TC. I only like chevys so i got the SS/SC because it was something new that i liked. I had just came out of a bad wreck with my 72 Monte SS. Im a Monte fanatic but i cant complain about the Balt. I really like the car. I still get 29.5mpg even with 89. Doesnt matter how i drive.

 

i get just under 40 on the highway on the stage tune, with a2.9" pully and full bolt ons. the difference you get with premium makes it more than worth the extra 2 dollars to fillup. youll save more money going that way believe it or not.

 

I have already gone thru two full tanks of 93 and ran fuel injector cleaner. Its still stuttering and vibrating. Im taking it to the dealer sometime next week. I cant figure it out its got my head hurting from trying to go from one thing to the next

 

thats just what theses cars do. Try running 60s and tell me how stiitty the idle is.
