Oil light keeps comming on when idling at light

[SMD69]

WHen my car is cold it is just fine.

After about 15 min of driving when I stop at a light or sitting in park my oil light comes on at about 700-800 RPM's

I have to give it gas to almost 1000RPM's to get the light to go out.

I took it to get an oil change yesterday and it still does it.

I checked the oil and its fine.

My CE light is off

I hope i dont have a bad oil pump

Thanks,

Your engine should be idling higher than 700-800 rpm. Reset your idle speed programming. What grade of oil are you running? Since we are out of freeze season where the temps can get below zero F, you could be running 10W-30.

Still, that is a rather elevated rpm to not have adequate oil pressure. Either the pump is weak, the pressure sender is inaccurate or the rod bearings are worn.

My reciept says 10w30 GTX performance oil.

How can I tell which one is cousing the problem?

Also How do I raise the Idling Speed on it, Please?

Thanks

Actually, the drive idle RPM for a Gen 2 ATX is 700 rpms under the factory programming, Scott.

I'm assuming the vehicle in question is an ATX, since he mentioned "sitting in park".

1. Easiest thng to do is rule out the sender first. This may require it's replacement. You might also try cleaning the connection.

2. If you still get the oil light after that, it time to change the rod bearings. Even doing this is not really expensive at all, just a little bit of labor involved.

3. If you continue to get the oil light after changing out the rod bearings, then you have some harder decisions to make regarding your SHO motor.

Resetting the idle...

You can find the instructions for resetting the idle here:

Just throwing it out there in case you want to try that first...it only takes 10 minutes and it's free!

Good luck!
