I have a 94 blue pontiac bonneville SE which has had check engine light on it since i had it. Dont know how I got through inspection and emissions. The code was 41 which most of you know is the camshaft sensor. Well I replaced the sensor, fixed the magnet, the crankshaft sensor and still no good. I remember reading one time about the coil packs being on the same circuit along with the ICM. I am wondering if it'* one of the coilpacks since my car stutters around 1500 to 3000 rpms pretty bad and sometimes when idling it can stutter pretty bad. I took it to a transmission guy who said he thought it was the torque converter slipping around 1500 to 3000 but I'm startin to think its the coilpacks, hence the cel. ANy info?

have you done a tune up? maybe it'* the wires...

I have a 93 SSEi and had the same problem had a tune up and changed the wires still a problem so i changed the coil packs it solved the problem. it runs nice and smooth now. I would sugest replaceing the coil packs. I got a complete set from the auto wrecker as they a expensive from the dealer.
