View Full Version : Bitchy Problem with my SR

So a couple days ago i thought it would be a good idea to wash my car and clean my motor. i did all of this in a heated autoshop. i even left the car sitting in there to dry for at least 2 hours. I then drove the car back home and let it sit in my driveway which is <32 deg. f. The next day the car started right up and i drove it all day. later that day all of a sudden the car would not react to throttle input anymore, and bog down to the point of stalling. i cleaned all the plugs and connections and it seemed to run fine again, until i floored it again and the car stalled again. everytime this would happen, i would try to start the car, but the idle would become soo low and lumpy that it would imediately die. i noticed quickly and lightly tapping the throttle kept the revs up, but then letting go of the throttle would result in a stall. my consult port checker tells my the CAS is bad, i forgot if it was code 11 or 21. i took off the cas cover and it looks clean in there. could it be water in my wiring? whats going on here? i need this thing done so i can make it to my gf's debate tournament tomorrow. thanks guys and gals

Check your vacume lines. Your problem sounds similar to what I had a few months ago.

you should definetly check for water in connectors, however just because the cas "looks good" doesn't mean the electrical components aren't failing. the pickup could be bad. you might try the "tap test" with the vehicle running try tapping various components and see if the running condition changes if so replace it. good luck!

ok guys here is the news:
i swapped my MAF with another MAF and it changed nothing.
i swapped my CAS with another working one, and nothing changed.
i tore apart every wiring harness that is related to maf, cas, and tps, the reason being as follows:
when i have the key on accesories, and push on the throttle, i notice the TPS voltage correspondingly going up on the display. but, i also see the injector voltage going up, with my input on the throttle. when i quickly slam on the throttle the injector voltage climbs from 5.4 volts to 13 volts for a split second, if i step on it slowly, it stays at 5.4 volts. This leads me to believe that there is a short somewhere between the injector power wires and the tps wire, because with just the accesories on, there shouldn't be any power going to the injectors. (no matter what, injector duty cycle still reads zero btw)
all in all the car has improved significantly, it can hold a rather rough idle, and drive almost 95%, and pulls strong in the higher rpms, and is no longer throwing codes. i think the water that was creating the short has almost evaporated. i am letting it sit in a heated garage overnight to see if that makes a difference. any more input? i need this car fully reliable by 12 pm EST tomorrow. thanks
