I havent posted in a long while and thank the board for my past birthday wishes!
I have a beautiful 94 seville sls that has a completely new suspension from wheel hums to struts to tie rod ends to swaybar bushings and everything in between. I started getting a "engine hot" message with the related cylinder cutouts with the engine being at operating temperature and no overheat.
Changed the water pump, thermostat, temp coolant sensor, etc and it went away until one day i went over a minor bump & got the same message for a second (still with the car at normal temp). I took out the pcm and put my prom in a new one thinking that it could solve the problem, but got a lot of crazy codes. I put the replacement prom in the replacement pcm and things settled a bit (fewer codes).
I am AT THE POINT WHERE I NEED A CHART OF VIN SPECIFIC PCM VALUES SO I CAN GO THROUGH THEM ONE AT A TIME. I WILL PUT THE ORIGINAL PCM BACK IN FIRST. I need a factory vin file of values if one exists.
I will pay if it is for real-thats how frustrating it is for me at this point.
I cant be the first guy to go through this, and if I am, somebody give me an aspirin and an award!
