Have you considered that maybe the miss is a bad coil, old plugs or that one stray plug wire that is laying on the exhaust manfold without any coating?

While that last one is a joke..it'* quite possible.

On the crank SENSOR code, was this code cleared when scanned?

the code should clear when the batt is nuhooked or no?

No.. not necessarily. It takes a certain amount of time..but history needs to be cleared or it will always show up.

how can i test the coils

Click on the Techinfo link at the top of the page.

still no more ideas why this 3800 missfireing?

Please give us an update. Did you test the coils? What else have you tried?

Did you replace your crank sensor? Clear the codes to see if it comes back? Check the wiring to the crank sensor?

Have you done a tune up with plugs/wires etc.

what i tring to do is get as many ideas as i can seen i work lots and havent ad much time to tinker with it was hopeing to have a few so when i get time this weekend to look at it i could just dig in it didnt want to have to run to the pc every to mins cuse that way i wasnt bothering all of you every 5 mins during the week end
