Hey guys wanted to get some opinions on an issue I'm dealing with. Roughly 2 years ago I replaced the TFI module plug, cause it broke apart. Spliced in the new plug from Blue Oval industries, and did fine. Last summer, I was having an occasional cutout that lasted half a second, and would happened just randomly. Feels like the engine just tuned off and on very quickly.
This got worse later on and parts had to be replaced.
Fast forward to now about a month ago, after replacing a distributor, ECU, module and coil. The half a second cut out is happening again. Noticed yesterday, it happens when I punch it. But goes away when I back off. I've done some research on this trying to something that will help and one thing crossed my path was the RF shielding that is on PIP, SPOUT, and neg, going to the TFI module. I never replaced the wire looping around those wires, and the foil. I spliced in a copper wire to the existing wire and wrapped it around those, close to the Module plug and wrapped it back up with tin foil.
It helped some, but still randomly with the quick cut out. I'm able to punch it and once at a high enough rpm like 4K in 5th. I'll get a single blip. I think I'm on the right path, but need to correct this. I've code scanned the car, KOEO got me a 15, 96, and 11. Not worried about the 15, since that is due to the Moates QH chip in the ECU port. KOER, got me a 20 cause my idle is a little high. The parts that were replaced as stated above were bad. ECU had two leaking capacitors with one broken connection, the distributor had a broken plastic connection connection inside, and the old MSD TFI coil finally bit the dust. I have checked my grounds, they are tight and clean.
Is there anything else to check before I start breaking out the volt meter?
