I've gross polluted here in Cali and had to go to the referee. It was actually great. We went through the whole motor and he showed me what to fix.

I don't know your car, but almost all the electronics can usually be tested for resistance values. Like the oxygen sensor. I've always had luck cleaning stuff as opposed to replacing. Toyotas have that sensor kinda like a MAF, right after the airbox. Those can always be cleaned up and run.

Just some thoughts. If not, it's usually about $250 to pass 😏
