Lexus Troubleshooting Questions? Ask a Lexus Expert
Hi Im David, thanks for visiting the site. those are all you back bank cylinders....interesting. I got to recommend a backpressure test on the exhaust to see if that cat is clogged. and also a compression test on that rear head.
oh crap thinking of toyota 3.0
this is your engine?
ok, im not familiar with that engine. ill opt out and allow another tech to chime in.
do the misfires happen all the time or only when warm?
it is how the system works since it only has 3 coils and three wires. when was the last time the wires and boots were done.
what brand do you have also what brand coils what about the plugs?
and silly question but are you sure the wires are routed properly from the coils?
does your check engine light flash
just to verify what wires are going from which coil to which cylinder
okay i just wanted to verify. it could be a crank sensor causing this as well did it have this issue before or after the changing of the wires and were the plugs done?
i would start with the crank sensor. and why did you change the vvt solenoid?
sounds good let me know how things go.
