[QUOTE="SnakeBit!, post: 1590300, member: 19474"] I have not had the cluster rebuilt....yet. I did have a code for that on the Forescan. in addition, it has acted up.....start the car and all the gauges go to zero and then maybe 10 seconds later come back or when I start to drive. With AI though, with the combination of codes I got along with a battery high voltage code, hopefully we narrowed it down to millisecond high voltages spikes that the PCM reacts to causing a disruption in the information received which it reads as coming from the heated PCV and the Throttle control module and makes it go to forced engine shutdown to prevent a runaway. I have two used alternators I got several years ago for a P71 so I through one of those today and cleared all the codes. We shall see. I had unplugged the PCV in hopes it was that but it shut down after that too, so apparently the PCV is not the issue and with a new throttle body, pedal and a bunch of other stuff, I have partially rebuilt the car chasing this ghost. This AI program has been unbelievable with the information I have provided including screenshots from the Forscan. Thanks everyone for your thoughts and staying with me on this. has been super frustrating for well over a year now, especially driving everywhere on high alert and trying to always position myself for an escape route. staying to the right, near turn lanes on either side or large non vegitation medians.
