I have searched and searched, read just about every thread on this forum and others regarding the lightening bolt of death, annoyance and pure frustration.
A little backstory to the JK maybe to better help diagnose. 08 JKU X package, 3.8 avenger Supercharger, 42RLE auto, Rubicrawler, 05 super duty front, 14 bolt rear on 40's.
Installed the Avenger supercharger almost 3 years ago. had the lightning bolt once early on and never saw it again for about 2 1/2 years. Then it came on frequently. I changed the Throttle position sensor, nothing stopped the lightening bolt, changed the gas pedal assembly since I read that was an issue, didnt change it. Read one guy even replaced a damn harness to solve the issue, checked with a multimeter on ohm's and the wires do not have a short in them. All are good. The connector seemed loose so I used a tad bit gasket maker, let it dry and the additional "rubber gasket" now has a tight fit. That didn't work.
At this point I am not sure what to do, Is it a bad PCM? Is it tuning related? is it Supercharger related? (Alasha has no issues with his Avenger) Could it be Vacuum leak related? What else could it be?
I am stumped and would do an LS but I am pretty in with this setup with the rubicrawler, supercharger and just rebuilt the trans. I think an LS is inevitable but I would like to solve this damn lightning bolt issue once and for all.
Lastly, the symptoms is the lightning bolt comes on (can be idling, or driving, it doesnt seem to matter) I lose all power and the only way to get rid of it is pull over turn it off and back on so it resets, it is intermittent and doesn't seem to have a pattern.
On the scanner it will switch from CL to OL Drive for fuel system 1 and short term fuel trim just zero's out and stays at zero.
Thanks in advance!
