hey guys it's been a while since i posted last.(cars been working to good) i just moved from missouri to arizona. there happens to be a large discrepency in altitude and the car don't like it. the car is an '84 vicky 5.0L with the crappy half carb half fuel injection throttle body system. since i moved here(drove the hole way.) the car has been running ULTRA RICH. i might as well have and injector installed in the tail pipe. when i come to a stop light i may as well stick my head in a gas tank the fumes are so bad. i've looked for a leak,but none are to be found. the gas smell is definately from the tail pipe. i just got a new motor put in this car and i don't want this to wash out the cylander walls. plus this baby is killing me at the pump with gas at 3.75 a gallon. i'm getting like 13 mpg. how do i go about adjusting this so it runs much leaner? if the car is suposed to adjust automatically it's not. so i need a way to manually do it. any suggestions????thanks.

You don't 'adjust' the CFI for altitude. More than likely, you have a MAP sensor (which is what this sensor does) that took a dump, or is dying, or possibly an O2 sensor going out. My first guess is the MAP sensor, however.Originally posted by raser13 View Post -
i would think so to but the car ran great in missouri. then as i drove across country and started hitting the mountains, thus climbing altitude, she started running rich. i was told that it can take a day or so for it to adjust itself but it's been three weeks. i wouldn't have thought that a map or 02 sensor would die just because i climbed in altitude. but i'll check 'em any how thanks. any other sugestions?sigpic"I love it when a plan comes together."

pull trhe battery cable and reset the ECM to defaults. It might just fix it. The MAP doubles as a baro sensor. It reads that info just prior to startup. Might not hurt to turn the key to 'on' for a couple seconds before cranking so it learns that info too.86 Lincoln Town Car (Galactica).
