Sleek 93 SE Posted September 18, 2005 Report Share Posted September 18, 2005 Well lately I've noticed a bunch of problems Im having with my car. It is getting horrible gas mileage, it idles rough, the speedometer is way off, it doesnt even have enough power to spin the tires anymore. My battery is really shitty and always goes dead and barely has power, im thinking this could be one of the problems, but is it possible that maybe my computer is shot? Any input is appreciated. Thanks Quote Link to comment Share on other sites More sharing options...
Regal_GS_1989 Posted September 18, 2005 Report Share Posted September 18, 2005 could be a just a bad connection from/or a weak battery. If there is a bad connection, or weak battery, your alternator will be working alot harder to power the rest of the car, which puts more strain on the motor, plus the lack of voltage can cause computer glitches, which can cause all the problems that you listed.

Grand Moff Joseph Posted September 18, 2005 Report Share Posted September 18, 2005 I'd switch to a new battery first, then re-diagnose your car. As far as the rough idle goes, check all of the vacuum lines. Quote Link to comment Share on other sites More sharing options...

Sleek 93 SE Posted September 18, 2005 Author Report Share Posted September 18, 2005 Thanks Guys, Ill try a new battery. I'm sure it probably needs new plugs/wires/o2 sensor aswell. Its got 94k and I don't think they have ever been changed. Quote Link to comment Share on other sites More sharing options...
OldSkoolGP Posted September 20, 2005 Report Share Posted September 20, 2005 When my speedo was ogin whacky on me one time, I found out it was due to an exposed power wire contacting bare metal. It had actually started welding itself to the body! Along with a new battery and alt. check, check your wiring, especially if you have put in a stereo or any extra electrical goodies. Can never be too careful. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted September 20, 2005 Report Share Posted September 20, 2005 The analog (and digital) clusters for our cars are alwasy very innacurate. Unless you have a prefect one to replace it with or have HUD, i wouldnt worry about it. I always went by my HUD when i had the analog dash.
