My gas gauge is shifted up half a tank(empty=half, half=full, full=past full), rpm gauge works wen it wants to and jumps around a lot, oil pressure doesn't work at all, and speedometer jumps a little when i'm cruising at a constant speed. Where do i start people?

 

being that they are all messing up i would start be looking at the gauge cluster ground, then take it out and look for any water damage or heat damage in the circuitry and plug. try taking the wires lose from the ground junction on the passenger side wheelwell and wire brushing the wire ends and cleaning the connections surface. its kinda by the battery. last thought, check the gauge fuse in the fuse box for any sign of damage or looseness.

 

its really loose, and i appreciate it, i just bought it so im tryin to start from the ground up, i have a bad miss when i hit 80-90 also, u know what that might be?

 

have u changed the oil, oil filter, plugs and check air filter. be a good start with a new used car. that if it looks like they have not just been changed. i doubt very much the plugs have been changed in a while. lol. can be an all day ordeal if its the first time.

 

changed oil, plugs, oil filter, and air filter is a k&n cool air system. i think it might be something more deep inside lol, i hope not though, it runs fine until i get to those speeds, then after that it runs fine, tranny?

 

plug wires would be next guess. how do they look? find a dark place and open the hood and look as best u can at the wires and see if there all lit up. dont be sticking your hand in there were it can get chewed up.
