Oh god if you really exist please tell me why when I took my truck in for smog does it kill the engine when the smog machine starts its testing? Took it to 3 different stations and all had the same result... DEATH! I pulled the banks 6 gun, ottomind, edge, MSD, Turbo timer, Propane inj and anything else I had added on with no luck, im at a loss and stuck. Production date of 3/98 and apparently im not the only one with this issue, I do know I can venture to the dark side AKA extra $ but budget is tight at the moment plus im just curious as to WTF is causing it. the OBD port itself is working fine because of the fact I can check for codes with my scanner. If anybody knows anything about this issue I would greatly appreciate it as I am getting sick of these $66 meter maid tickets due to exp tags.
