Ok...I have a 2010 Camaro V6. I threw a code for cylinder one misfire. I bought a spark plug...same code. Switched coil packs...same code along with throttle body. So I bought a new throttle body...same...

throwing parts at is a waste of money. misfire can be one of 3 things. cam sensor or crank sensor or fuel injector. other things can can be a air leak too much air in the intake or leak in vacuum line. can also be the timing is out.. this can be the adjuster weak.

It's on the throttle-body, probably opposite side from throttle cable and lever.

Any Codes?

Check for vacuum leaks with a can of carb cleaner engine running - when engine race up or bogs down there is a leak. Spray all around intake, vacuum hoses, brake booster, and throttle body.

Engine idles high like it has a automatic choke,runs rough and very rich at idle. Code 35

first thing to check is the base gasket on the bottom of the throttle body.if it's sucking air it will idle too high.if that's not the problem the you likely need a throttle posion sensor.
