I have a 2005, replaced the engine with same year, (timing belt broke). Replacement engine is running great BUT on idle is shaking a bit WHY? Replaced plugs, wires, swap coils, swap many sensors, clean intake with seafoam, check valves with vacuum gage (very stable), timing marks ok, clean crank sensor, no vacuum leak, what could it be?
Ran out of options, thinking to take it to the dealer to adjust the timing thru the computer, Any ideas? I getting crazy here thanks
