Post Help ! Ss/tc problem !

Hello,

I have a 08 SS/TC and it has a very bad idle, it run between 750 and 1000 RPM and it wants to stop running when at idle. This morning, in all gears it was like it doesn't take his gas and when I put a little bit more on the throttle it does like 45 backfires in 3 seconds... I got a check engine, I will check it when I will be back from work... Can you help me ???

Thanks !

yup, need the code. Sounds like a massive/major missfire issue.

Also post up mods you have incase your tune or mod is causing it too.

Please ELI5, when you say "pull the code", you mean OBD2, right?

Yes, any generic scan tool will read the error code.

Ok... My bad. I did not read the full OP text stating that the check engine light showed up. So I was wondering how to check a code without that.

Thanks for the clarification.

Misfires.
"If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors. Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

How many miles? Have the valves ever been cleaned? How old are the spark plugs and which ones are you running?

New set of OEM AC delco spark plugs. Move the coils on 3 and 4 to 1 and 2 and see if those Misses follow.
