What is your question?
I have an o1 is300 I recently changed valve cover gasket, spark plugs and wires, I replaced all the vaccum lines on the throttle body, plugged everything back in go to fire the car up and it's misfiring, cylinder 1,3,6 one of the coils was sparking outside of the insulator so I replaced it. Still misfiring, cleaned the maf sensor very well, still misfiring I give up..
What makes this problem better or worse?
Nothing
How long has your 2001 Lexus IS300 had this problem?
A day
It's impossible on the is300 to do that. One long harness for coils plugs only meet there designated coils, possibly bad coil packs?
No problems before valve cover gaskets were installed... I have no idea - without personally doing the **hands-on** testing.. Good luck!
I gotcha. Ya car ran cherry before I did the gaskets. I'm stumped
