hmmm, did the KOER test. All that it keeps saying is code 73, which from my understanding means "User Error", somthing to do with the full-on throttle phase not initiating correctly at the final part of the test? Ive done the test 5 times, and each time i push the gas pedal all the way down, which is reving the engine to around 5-thousand RPM's and im quickly letting off, like was suggested... This is the only code, and its repeating itself twise to me. Im not sure how i could be doing anything wrong? Also with the KOEO test, all im pulling is 111, and 111, than another 111, 111??? Im guessing this is saying that there is no reported problem? Engine is FINE? Question, If the alternator is going bad, would a code be able to be pulled showing this? Ive noticed somthing while tinkering with things today. While the engine is warmed up, if i turn on the heater it causes the engine to start running horribly. Now usually if the engine is warmed up the engine runs smoother, and better, unless i turn on the heater. Its instant, just as soon as i turn the heater on there is a drop in the idle speed, a swift surge or drop on the amp/volt meter gauge thing (aka battery gauge on dash) and the RPM's drop and started fluctuating just like they do when i first turn on the vehicle when its cold and not warmed up yet??? I repeated this over and over and over, untill finaly it even made the engine die once. I even started to notice a white smoke coming from the exhaust as the engine was acting up like this. My guess is one of two things... Either the Alternator is going bad and when i turn on the heater it is pulling a draw on the system that it cant handle, or there might be a short somewere?? COULD THIS BE the main issue ive been faceing the entire time? Would this show up on the KOEO/KOER test? Thanks, Jason.
