The ECM was a guess at this point. I have a friend who is working on his a car a few weeks ago, had some idle issues and a popping, swapped ECM's and it cleared up, so, a random guess to be honest.
The fuel pressure went to nearly 40 on the gauge under the hood. It's set at 40 without the vacuum
I will test the injector plug as you stated., and the spark plug wires. I will also re-recheck the plug wire firing order again. I'll get the balancer to zero and recheck the wires and the distributor position.
The popping was very random and not often at all. I never knew when it would happen, I swapped plugs and no change. The spark plugs were VERY clean, only a black ring around the base of the plug. The ceramic was white, the electrode was pretty darned clean as well. All of them looked identical. No cylinder had a different look to the spark plug. I have the vacuum on the FPR as well.
Yesterday, the car started fine, ran fine all the way to work, and only gave me an issue as I turned into the parking lot. Then just died and wouldn't start as I stated.
I replaced the ignition switch last night in the parking lot as a "let's just see'. No change.
I had swapped the Trick Flow R intake a few weeks ago to a Trick Flow Track heat. Could a bad lower intake gasket be a possibility.Just something I'm tossing out there.
