Callin the smart guys....
Ok here is a new one.... A few weeks ago I seen that my volt gage was reading low (12.3 - 13.6) I changed the plugs and wires and then it was reading fine (one wire was split). Now in the past week I have seen my digital water temp gage was all over the place, jumping from 180 to 90 and every where in between but this was intermittent and the analog was reading fine. Now tonight I was playing around and I found out something new when I push down on the accelerator (past half throttle) the heater fan shuts off. And the car started to stall out on me at low RPMs. Oh yea and the volt gage was back down to the 12's. Any ideas and what is going on?
it's fixed here is what was wrong

I just chased down a similar problem in my 95 bonniville. After replacing alt. and checking the complete wiring harness, I gave up and took it to a service garage. 1/2 hour later, found a bad ECM! I replaced the ECM, and car is back to normal! Not sure if it is your problem also, but worth checking out. :cheers:

Re: Callin the smart guys.... (fsr402)
The reason you only get a 12 is because the ECM will not tell on itself. As far as your Volt gauge, plugs and wires will not have an effect on its reading, as it is reading your charging system and not your ignition system.

I had a similar incident a few months ago. One of my plug wire boots had melted through and was sending the spark to the exhaust manifold. My digidash went :crazy: ! It would go dim, bright, normal, with the LEDs going from a regular display to nothing to ALL on. I replaced the plug wire and everything has been fine since.

In addition to grounds don't forget that sometimes we have to clean the battery cables........ even though they may LOOK clean the only way to tell for sure is take them apart...... don't forget to pull the screws out and clean behind them ........ a little grease in there helps too :seeya
