I'll keep it direct. 2004 LC, bought a couple of months ago, has recently been having intermittent issues with ignition coil codes thrown. An independent shop told me they believed it was an ECM or PCM issue due to the lack of pattern in oscilloscope data and no other issues found. Toyota tech then couldn't find anything wrong with it, he believed it could have possibly been tuned, but couldn't verify. He didn't want to take the whole thing apart and told me he thinks it's a wiring harness issue.
Long story short, I think it's not properly diagnosed, and I need recommendations for someone in Arizona or the southwest who specializes in electrical gremlins. But if it were a wiring harness, where would I start?
