Hey peeps. My car is acting goofy on me. Sometimes when I'm at idle, say like at a red light, it feels like my engine is somewhat rumbiling or shaking. I've checked the engine mounts and they are ok but it seems like it is coming from inside the engine. Now it just started happening and it happens SOMETIMES. Anybody know the cause? I also about 3-4 months ago blown a head gasket so I dunno if that would have any affect.

have you checked your spark plugs? sounds like it could be misfiring, my cars engine shook so much that the exhaust was actually moving back and forth when it was misfiring

does your RPM just around while at idle or while driving? If so, it could be you EGR valve,

check your MAF...my car did the exact same thing after i put my intake on and i had it on backwards.
