I took it to auto zone they don't check it anymore found the service plug it has 3 wires going to it which wires should i jump? Now the car was running like it had a miss fire running rich i looked around and notices the vacuum hoses looked weird so i flipped them and the motor ran normal so i turned it off and started it up again but this time it took a little to fire up so i shut it off and tried again but didn't turn on. i notice the injector is not working is there a fuse or a relay that controls it?

I just tried two injectors hoping that my injector had fried or something but the injectors aren't firing ether. i grounded the blue wire which is the pulse that controls the injector and it sprayed gas . does any one know what could cause the pulse to weaken or can all these injectors be bad also?

i figured out what my problem was with the injector the wires were repaired before and the blue wire came loose so i hooked it up and it fired up, so now i have to figure out the how to read the codes and find a code list?does any one no what the spark plugs are suppose to be? the hood says 35 but couldn't drive the car at all.ac delco says 45 ran better but the car falls on its face every time i floor it, i pulled the plugs still running hot. Already gaped them at 50 and it seems like it still running to hot, im just going to keep opening them until it starts running rich hopefully i can figure it out that way
