Car stumbles throughout RPMs???
It is a 2.5 throttl body 4 cylinder. It sounds like a ignition miss but all ignition components are working. Plugs, wires, cap, rotor and module are good. It is rather annoying. The engine bogs slightle there is a engine speed drop. It is very intermittent with no pattern.
What could the problem be.
