I reacently crashe my 2000 monte carlo ls. I fix the exterior, and they said the engine was fine, But lately i been notecing a drop in the rpm meter when im at a stop. and and times my car goes back when i release the break on a slope. It used to move a bit more when i realese the break then now? Could it be my breaks, or worst a head gasket?
I thought it was the idle also
