Thank you all for the info. I've run the van very little this last year but picked up the work in July/Aug this year. This is what I've done. Replaced the MAP, PCV, fuel and air filters.. also new gas cap as the original was lost. Changed the oil but havent done a thorough tune up (needs it, btw, badly) The problem started again about 3 weeks after. Here are the codes I was able to pull: Remember, the voltage regulator is currently hardwired outside the computer, so some of these codes are expected.
12- Battery power to PCM disconnected
41- Generator field not switching properly
51- Right rear (or just) fuel system lean
46- Charging system voltage too high
51- (came up again)
then the 55 ending code.
When I checked the oil (changed Aug 8) it was BLACK BLACK BLACK and smells strongly of gas AND is heavy over the fill line. Removed the doghouse and it looks like there's fresh oil or gas that has leaked or sprayed.
New MAP may be defective. Will need to replace the computer. Any ideas are appeciated. Thanks!
