Could a bad cranksensor make my V10 have a real bad misfiring problem,,the engine feels like it is only running on 6-8 cylinders.I have replaced plugs ,wires,coils.. Want to get as many ideas to look at,,have to work on it in the driveway,,should be about 30 degrees this weekend!! Thanks to all that respond!!

 

Are your coils separate from the modules? (also, you should keep all this stuff that's related in one thread.... makes searches more effective.)

 

I have been told they are in the coil packs,,sorry for not doing this right,,I read that you want different topics in different threads,,but I see your point!!!!

 

Meh, If I comb my hair right, no one will notice......

if you are missing on four or more cylinders, I would HIGHLY suspect one of the ignition modules. What ya really need to do, is figger out which cylinders are missing.

 

my truck would lobe and run rough (felt like a plug was out or disconnected), howl out of the IAC, and would not go anywhere with the gas peddle down. at first i thought replacing plugs cap rotor ect ... turned out to be a bad crank sensor.

 

Hello,,I thought iwould let other V-10 owners hear this,,,,After weeks of checking all my wiring and replacing all injectors also,,my problem came down to a coil pack that had less then 50 miles on it,,It would start out ok ,then as it got warm,,everything went downhill,,Mis-firing,,shifting wrong ,totally cutting out,,... Found the bad coil pack was sending most of it's volts made for the plugs back through the computer,,replaced the bad unit,,Burning the blacktop up again!!!!!
