Re: camshaft sensor
This may sound like a stupid question, but type of spark plugs are you running? Waste spark systems sometimes track the wasted spark voltage and duration to calculate crankshaft and camshaft poitions mathmatically and with single sided platinium plugs they will get a funky signal which the computer interprets as cam. pos. sensor issue. This issue actually quite common on the Saturn S-Series.
