1994 buick lesabre 3.8 V6 misfires through intake manifold. I replaced the harmonic balancer, timing chain, spark plugs, crank shaft position sensor, repaired wiring to cam shaft sensor and crank shaft sensor. What could be the possible solution to the problem. Could it be a defective crank shaft sensor? Or bad wiring? Please help and thanks. I've been working on this for 3 days and it is stressing me out. Thanks

When you replaced the timing chain and gears did you replace the magnet that snaps into the cam gear to trigger the cam sensor?

No I did not replace the magnet, but when it was removed from the old gear it was magnetically charged and stuck to metal. Any suggestions? Thanks so much.

Unfortunately it's time to take the front cover back off and install a new magnet. Has to have a magnet to trigger cam sensor.

I will try that. At my wit's end with this thing. I appreciate the advice.
