Throttle Body replacement

Hello again,

Just out of curiosity, what size cam do you have in there?

Thanks,

Hello,

Yeah buddy. Anything over 0.50" lift is a hot cam. That's quite a lot of duration as well. You can certainly just replace the Idle Air Control valve (IAC). It should just have two bolts that hold it in and one electrical connector that connects to it. If you want to replace the throttle body, that's up to you, but I doubt it has anything to do with this.

Thanks,

Hello again,

I don't have a specific vehicle with an LS2 engine in it that a look up quickly for the relearn on the Throttle Position Sensor, but the MAF I'm not to sure you want a screen on it. I'm almost certain that you have a blow through style MAF so the platinum wires should be protected, and a screen will slow the air down entering the engine. It's like the opposite of running an engine like yours without a windage tray. It just doesn't make sense, but if you want you could add a screen, it's up to you. Where did you pick this car up at? I am going to hand you off to an expert with a little more experience with Chevrolet, I'm a Ford man myself, but I know a sweet ride when I see one, if if it's a Chevrolet, LOL!

Thanks,
Alex

As this is a Camaro that never came with that engine. I would have him try cleaning the throttle plate first with choke cleaner or throttle plate cleaner on both sides to see if it makes a difference. As far and the turn signals go check the bulbs in back as one filament may be hitting the other lighting all of them up. Quite common in those year cars.

This engine did not come with a IAC valve. Can you please shoot a quick video with your phone so we can see what's going on? That would be great. You can upload it here with your response.
