The best method is to find out which doohickey doesn't like to heat soak. You need some method of systematic "testing" by spot cooling. In the olden days before the ozone hole, I'd take a refill can of r12 and go around spraying doohickeys, one at a time, with a start try after each. I've since used r134 refills, a garden sprayer with ice water (real good with a fine stream for getting at hard stuff), canned dusting air (takes too much), Liquids or refrigerants are the best options.


Okay now it doesn't matter if hot or cold. It just happens at random- Run good-ish and or horrible. If I floor it the RPMS go up but has no power and will sort of do something like a muffled backfire that feels like is stopped by the CAT. I am at a loss. I have swithed all relays and sensors with used or new except the Crank, Cam and O2 sensors. Is it possible that its something Like fuel pressure? Or main computer? maybe plugged CAT?
