Yes, a faulty OptiSpark can indeed lead to a Code 42, which typically indicates a problem with the crankshaft position sensor or its signal. If the OptiSpark is malfunctioning, it may not provide accurate timing information to the engine control module, resulting in the error code. Additionally, issues with the wiring or connections associated with the OptiSpark can also trigger this code. It's essential to diagnose the entire system to pinpoint the exact cause.

94 z28 camaro with a 5.7 liter 350 lt1 and it has the 460le auto trans recently purchased sat for a year in a garage this car has no power poor acceleration any ideas?
The problem could be your optispark distributor. They have a tendency to corrode inside and when this happens, it hinders the performance to the point that acceleration is greatly hampered. A bad optispark will also cause starting issues and engine misfires. Besides the optispark, check for a vacuum leak. Intake manifold leaks are very common on the LT1, as well as valve cover gasket leaks.

OBD1 code 36 is a high res failure. Due to a bad or failing optispark distributor. My 95 has this same code and still runs but the optispark is not sending a signal to the pcm. If I crank the engine for about 7 seconds it will start every time.

Double check the ground, and make sure the cap on the Optispark unit isn't what's arcing instead.
How can you tell that your optispark distributor is going bad?
You can tell that your optispark distributor is going bad if you experience symptoms such as rough idling, stalling, or difficulty starting the engine. Additionally, if you notice a decrease in engine performance or misfires, especially under load, it may indicate a failing optispark. Visual signs like corrosion, moisture inside the distributor, or burnt connectors can also suggest impending failure. Finally, using a diagnostic tool to check for error codes related to ignition can help confirm the issue.
