So you are saying that there is probably 2 different problems, and not just a problem with the module causing both codes.? I guess that makes sense, I assumed since the cam sensor ran to the module and I replaced the cam sensor it was the module causing both.

We tested for continuity from both the cam and crankshaft sensors to the ICM and the computer under the dash (ECM?) and they all were ok. I didnt check the resistance though. Wished I would have now.

I am tempted to just yank that bulb out of the cluster and not worry about it, but I hate to do that, mainly because I hate doing things half *** and I hate giving up on stuff.

Not 100% sure whats going on there... But at the same time I have the spare parts which gives me the luxury of throwing some parts at it to solve the issue...

Is the Cam magnet( interrupter ) still in the cam sprocket?

Code 41 is for the Cam Circuit, so the ECM is seeing an issue there

Code 43 revolves around the Knock sensor circuit...

In the past I have had multiple codes... 43 was one of them, as well as 42.. But that turned out to be the ECM..

In your case I can't be sure and I don't want to see you waste more $$ either..

I'm a little confused on this one guys.

He purchased a Delco type 2 ICM/coil pack setup for a 92-99 from me a while back. Said the ICM was DOA, another was sent...didn't hear from him for a while. Then got a PM saying the second was DOA and his mechanic replaced the ICM with a brand new one. Now he says he has a Magnavox from a junkyard on there.

Justin...what setup is on the car? This could change the troubleshooting and knowing the history of the mutliple ignition issues is also good and relative information. You might have another issue causing ignitions to go bad.

BTW..You have a PM.

The ICM was replaced by a Mechanic?

Did he give any reasoning why the code 41 and 43 are still coming up, and did he have any thoughts or ideas on what the issue could be? and how to repair the problem?

A link from your PC'* hard drive will probably only show up for you.

Best way to post a picture is to use a hosting site such as Photobucket and then paste the IMG tag here.
