Question about 1998 Pontiac Sunfire
My oil pressure light comes on when the car is warmed up and the idle drops below 600 rpm
SOURCE: 2001 pontiac sunfire
It sounds like there is a short in the switch that turns the interior lights on beside the headlight switch. You might be able to get a switch after market from your local auto parts store. Possibly with it being an 01, it would be a dealer item. Try calling parts store/dealer to see if you can locate one. Hope this is helpful. Please rate. Thanks

DOES IT HAVE A LOT OF MILES ON IT OR MAY BE THE OIL PUMP IS IS GOING OUT? THERE IS A SPRING IN THE PUMP THAT IS A BYPASS FOR HOW HIGH PSI IT MAY HAVE BROKE THAT WILL GIVE YOU LOW PSI.

To update my earlier repair on the 2001 6 cyl Escape: When cold, and when the ignition was turned over but no accelerator pressure given, the rough idle finally returned the P0303 code again when the check engine light came on indicating that it wasn't caused by the plugs or the coil. FYI, I had replaced the intake manifold gaskets during the original repair and just prior to that I had replaced the fuel filter which was very dirty (I cut it open to see).
The repair manual referred to fuel injectors as a possible problem. I have run three tanks of fuel using different injector cleaning products and am very pleased with the results. Cold starts are much smoother and I am unable to coax out the P0303 code or any other code.
My opinion, change the fuel filter, use a fuel injector cleaner for a couple of tanks, change the plugs if the problem still exists. The coils were not the problem on my vehicle.

ok. oil ight is probably nothing more than a faulty pressure switch.You can have pressure checked at same screw in port. 15psi is ok...just. very cheap to replace. Ign control module is probably the cut-out fault. You cant really test it; repair by substitution is the trick.
