i ran into a bit of a problem last night with my cam and crank sensors. i was at the shop last puttin in a cam and crank sensor because my computer was sayin intermitent loss of cam or crank. i put them in and it ran fine. i left for home and the CEL came on and the truck started bogging down. pulled over and started it again. started and ran fine so i pulled it into the hospital parkinglot and left it over night. be fore i left i shut if off and started it a few times. started and ran fine. i went back this morning to see if i could limp it home. it started up but then bogged down right away. i checked the pug ins to see if one was loose but they were all tight. a tried a few more times to see if maybe it would go but it never did. i havent been able to check the code yet. my only guess would be that a wire broke inside the harness so its not getting a good reading off the cam or crank so its just bogging? sorry for the novel i just wrote im just trying to get some thoughts and tips on what it could be. thanks

 

Did you disconnect the battery?

 

If you start it up, and just let it idle, will it start bogging? If it will, wait for it to start, then go push/pull/prod the various wiring harnesses, and see if anything interesting happens.

Check the connectors at the PCM as well.

 

no i havent disconnected the battery

and i tried wiggling the harness around to see if anything different happend but it was the same thing. i go to wright technical school and my teacher is a master tech and and he thought it maybe just bad wires

 

Well, not that it matters, but there are plenty of "master tech's" that don't even have a clue about the lower intake issue on a Magnum motor. So I wouldn't put all my pennies on what any mechanic says.

 

so what would you say the problem is? i cant think of anything other than bad wires but i dont know as much as some people.

 

Clogged cat?

 

cats gutted

 

Unplug the front O2 sensor then, and run it like that for a bit. (it will set a code... oddly enough... ignore them.) See how it does. If the problem goes away, replace the O2 sensor.

 

Don't know if it would or wouldn't help, but I mentioned the battery cuz everybody here says to disconnect the battery whenever doing anything electrical. One for safety and two so that it'll reset the ECU. That way it'll "learn" the new sensors.
