I bled the coolant fitting and tightened the vac fitting more on top of the SuperCharger and tightened the new gasket I just put in between the SC and throttle body a little more. It may have settled in the 3 days since I put it in. I also took out the MAF and cleaned it with a model paint brush dipped in CRC. I cleaned all sides of both filaments, rinsed it in CRC spray and put it in. Then I drove 80 miles this morning to work and back and it is running perfect. I bled the coolant a little more after I got home. It is finally acting normal. I think my mileage is back to normal. 28.3 yesterday on a 150 mile tank and at 100 miles on the new tank top off, the fuel gage is still sitting on full so I'm hopeful it's back the way it used to be. It seems like if it is fixed now, it was one big vac leak, a couple small vac leaks, and a dirty MAF all adding together to screw it up. Maybe the air in the coolant contributed too. I'm gonna cancel my appt with Buick tomorrow morning and check the mileage after about 300 miles.

Thanks Dave, I'll try these things you've said and see how it works. The car just runs so good otherwise I hope it's an easy fix. How do I get to the throttle plate axle? Can that be done without taking anything apart? If not what needs to be done to get to it? Thanks again

Rapid Parasitic Drain

The battery in my 1995 Mitsubishi Montero drains very quickly - in just a few hours. The battery is new and alternator seems to be charging, OK.
I have already tried pulling and replacing all fuses, relays and fusible links that I could find. I also tried disconnecting the alternator, starter and ignition switch but the volts would still drop rapidly when the + cable was re-attached. I have also tried chasing down shorts but haven't found anything obvious, yet. Any other ideas??

with a voltmeter across the battery, or amp-meter in-line, as you pull and replace each fuse, have you recorded what voltage bumps, or current draw changes have occured for each circuit? because the one that causes the most significant bump is probably the circuit at fault.
do you have multiple fuse / relay centers? for example, in my accord, there is one in the engine compartment, but then there are also two on each side of the lower dash.
do you have any power windows, sunroof or seats? those would be my first suspect.
another thing is possible here. that is your fuse / relay center is sitting in a moist environment and somehow shorting a hot circuit to ground.

One word of caution while trying to find a draw on newer vehicles. Understand that some modules on newer vehicles are "stay alive" modules and will show a draw for quite some time after the vehicle has been shut off before they will shut down.
Vehicles with things like cascade lighting, remotes, alarms and such will often have modules that are still "thinking" for upwards of an hour after the vehicle is shut down.

this is very true, but they most likely aren't significant current draws, certainly not ones that force a battery quickly down. maybe i'm missing your point.

I've got a 97 S-10 with the same problem.

Thanks. I tried pulling every fuse, again, just to make sure I didn't miss something and still didn't find the bad circuit. I have ordered a wiring diagram so I can make sure I'm not missing a relay somewhere - I already found some behind the dash. I also think it might be in the alternator cable - pulling the fusible link on that circuit stops the drain.

If you can disconnect the alternator and stop the drain, I would suspect the integral regulator in the alternator is shorted.
