Recommended Posts

Assuming the car otherwise runs fine, low/stuming idle is typically

A. IAC/idle air control valve inop or dirty as Hell.

B. Throttle body dirty as Hell

C. EGR malfunction stuck open at idle.

I have to keep Idel up When parked. Or I drop mid 12s and my rpm starts to move around. I just hold it a bit over 1000-1500 rpm. You should just do the same. Also not play at stop lights.

Like if I'm at a light. And play full tilt I drop voltage down to 12s then It will stay there until I push on the gas. Because I don't think the salt is charging at the 500-600 Rpm idel
