what would cause the map, tps, iacv, vss and o2 sensor to all error. Is there a common ground or wire between them that could be messed up? If i unhook the map or iacv sensors the car will shut off. so the sensors are doing something. the tps sensor really doesnt make a difference if it is connected or not. It hesitates really bad when i give it gas. when it gets hot it runs worse. I did have the vss wires switched is there a fuse or something somewhere that could have blown???

 

Sounds like a grounding problem. Do you have the thermostat ground on?

 

yep

 

Hmm... Check the schematics. See if all those sensors share a ground. If they do, you've found your problem. Check continuity between the ground wire on the sensors to the negative terminal of the battery.

 

not a ground problem.......
