Re: Jeep grand cherokee trouble
Did the symptom change after the tuneup?
How long has it been doing this?
Is it running really poorly causing it to idle low or is it running smooth just really low rpms?
Check for your plug wires in proper order, check your vacuum, if you have the ability, plug the pcv valve and the breather on the other valve cover, remove the dipstick and measure for vacuum on the dipstick tube. If you measure ANY vacuum here its time to repair the blown plenum plate gasket.
