Mike,
Before you throw $ at oil sensors, consider this. While the Aladdin shows flaky oil pressure readings, your dash gauge reads normal. Dave’s ET readout showed no oil pressure codes/issues. Since the Aladdin is reading the ECU, just as Dave’s ET does, that would seem to indicate a faulty electrical connection in the Aladdin circuitry and not an oil pressure issue. Maybe I missed it but I didn’t see any info on what code(s) the engine is displaying when the problem (check engine light) occurs. My suggestion is to quit chasing an oil pressure problem unless the codes indicate one.
