Angry 2002 lexus gs430 rough idle, misfire, ticking noise under hood

Hey guys,


So the first time I had to deal with this problem(less than a week ago) , I replaced the spark plugs and ignition coils and everything seemed to be working fine. Up until I started driving it a little more and give it more gas. As of now, the check engine light is back on and flashing. If I had just replaced the plugs and coils, what else might be the problem?

First thing, get the CEL code. It may not give you the exact diagnosis, but it sure will narrow things down.

Recheck all the electrical plugs/fitting for the coils and such, sounds like something is not plugged in correctly. Also, check for any damaged wires or vacuum lines.
