I recently had problems with my car. I replaced starter, prefuse box, crankshaft sensor, new spark plugs and two coils and finally had to get the ECU repaired by getting both in and out drivers replaced inside. This made the car start and the check engine light went away.

The car does not give any code or the check engine light does not come up but the engine has rough idle and sometimes you feel kicks and misfiring when stopped at the red light. The check engine light does not come up.

Can anyone suggest what could be wrong here or has experienced similar problem?

Intake manifold? Fuel pump?

But shouldn't that throw codes on check engine?
