rev and stalled.

hey all! I just changed the spark plugs today for my civic which has 324,000 miles. I removed the spark plugs to check the compressions on the engine. Prior to that, I removed the TB and cleaned the IACV which stop the idling issues.

I put on the new plugs today and when I rev past 3 k, it stalled. It was idling funny to. Any ideas on how to fix the problem? I ddi check for vacuum leak and everything checked out fine.

You sure you didn't mess up the spring in the IACV when you cleaned it?

Also check the gasket on the TB....make sure the hose to the MAP is secure as well.

no sir. It ran fine until I change the plugs. Could it be a new faulty plugs?

Could be, check the gaps on them
