I have been having an issue with a "lurching" when stopped at a light or stop sign. Seems the car wants to start driving off on its own. Brief occurrences that feel like the throttle is slightly pressed. Here is what has been done so far

Anyway I am down to possibly my MAF or EGR. I unplugged the MAF and the car ran the same. This I do believe indicates that the MAF is not at fault. So today I found this test procedure for the EGR

I did the test a short time ago and everything tests out except for the ohms reading. I had the EGR at room temp and I am supposed to get 8-9 ohms. My EGR is reading 6 ohms. Does anyone know if that is an indication that I need to replace it although every other test shows it is in proper working order?

I'm getting ready to change the gasket under mine and clean it real good. I'm thinking I got a tiny exhaust leak under it
