Ramdom Stalling

[Spy4uinc]

My 91 SHO is totally stock. It has approx. 195K on the 3.0L. The car runs strong and smooth, but has developed a random stall problem. It usually occurs when accellerating from a stopped condition. Sometimes it won't start right away after the stall. It can take up to 5 mins. then start right up with no hesitation. I ran the KOEO test with codes of 67 and 14. The KOER test was an 11 so no problem there. I replaced the ignition module and cleared the codes and ran the tests again with 11's on both. The next day it stalled again and the same codes were present.

any ideas?

Thanks, RD headbang

I dont have as much knowledge as most on this forum, but i would say that it might be the CPS shrug Can anyone else help him out?

The 14 would indeed be indicative of a CKP (or CPS) sensor failure.

Confirmed. The code 14 indicates a failing crankshaft position sensor. You can get this part as one of the following, but the replacement requires removal of the accessory belts, crankshaft damper and timing belt covers. There is greater room to route the CPS wire up through the tangle of wiring harnesses forward of the fuel rails. I route a speaker wire down through the largest holes, tie it to the connector end of the cable and pull it up through the tangle.

I just did this, so if you need a hand just PM or email. By the way, while you're in there you might want to consider doing your timing belt, water pump, crank seal, etc. (entire lower 60k)

Well worth it while you have it all apart. burnout

At least the CPS isn't that hard. Just takes a while to get everything out of the way to change it out.

And do a search for the "starter bump" method of getting the crankshaft bolt off. Even power tools don't like that bolt..

Good luck!
