Whats wrong with my truck???
Alright, so my luck has gone to crap in the last few weeks and I'm now broke so I don't have much money to just throw parts at my truck and i need it to run. Clothes washer broke had to buy a new one, had a pipe burst in my bath room that had been leaking behind the wall for awhile so I'm doing a bathroom remodel.. Don't mean to tell you my sob story but just giving you a bit of background on my situation with money :P.
Anyways, now that I'm remodeling my bathroom I really need my truck to run, and of course now is the time something has gone wrong with it.
When the truck warms up and i come to a stop it will die out. I can immediately start it back up after it dies. If I keep my foot on the gas and brake while stopping it will be fine... for awhile.. After about 5 minutes of doing this it starts acting like the timing is thrown off real bad while applying the brake and the gas.
It doesn't throw any codes at first, but after 5 minutes or so after it starts acting like the timing is off and it throws a p1391. Intermittent loss of cmp/ckp sensor.
Last week when it broke down I took it to a small mom and pop shop and the guy replaced the cmp and checked the plugs/wires. He had no clue other than thinking maybe it was the catalytic converter. I had just gotten my exhaust replaced 500 miles ago from the cat back. When I got it replaced the exhaust guy told me the cat was fine and didn't need replaced. But now when i get under and tap on the cat with a hammer it rattles a bit.
My thought is the crank sensor but I'm no expert by any means. I would just go buy the sensor and replace it but I don't want to throw the money away when I don't have it if its not the problem.
Sorry for the long post, but I really need my truck running. Any thoughts/suggestions are much appreciated.
One last thing... plenum fix has been done and front o2 sensor has been replaced.

I would remove the precat 02 sensor from the pipe and drive it...If its way better replace or clean the cat out (you can run a gallon of laquer thinner with like ten gallons of gas at 3,000 rpm for 20-30 minutes and it should clean it out to where it will flow enough to work again...) seafoam can help too..

Ok so when i remove the pre-cat o2 do I unplug it also or wire tie it up when I drive it? By doing this Im assuming its releaving some of the back pressure which should cause it not to die out after warming up?
Thanks for the response by the way. I'll try this when I get home from work and drop an update.

I recently fouled a new 02 sensor with soot from running too rich with different injectors so I sprayed the **** out of it with carb cleaner and it works fine now... maybe I got luck , maybe its something to try when an 02 sensor starts to fail...
Not that I think thats your issue at all...
