Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Hi im kevin if you start car and one by one unplug ignition coils to see which ones make the least difference to running
There will likely be 1 cylinder that doesnt react when unplugged .turn off and swap coil and see if missfire follows coil
Coil,plugs,injector are the most likely if not could be a valve issue.
