Question

Can multiple misfires occur as a result of a faulty connection in the ignition/key steering column? We've replaced plugs, coil packs, air flow tubing to no avail. It only happens when the engine is cold or left overnight

Answer 1

When this misfire occurs is there any upper engine ticking noise? And what is the motor oil level? Engine oil is important the engine uses a oil pressure for the camshaft adjuster. a internal leak can also be the cause of early morning misfire.
