I drive a 1991 Toyota Corolla LX with 193K miles and NO I haven’t had any acceleration problems yet. My problem is that after 15 mins or so of driving around, the Oil Pressure light comes on but only when idling. Such conditions include - When waiting at a traffic light - A little before co…

Oh. Also about the above problem. after the oil pressure light comes on, it goes away as soon as I accelerate just a little bit. This works even if I am on Neutral and stationary. Did I mention I am a student, and $50 means I need to work around my budget !

With this many miles, I would get it tested. If you are very lucky, the problem is a bad sensor, but this is unlikely. Your symptoms suggest worn out main and rod bearings. This can sometimes be cured with a new set of standard bearings, but only if the wear is almost all on the bearings, and not…

First check your dipstick. Is there enough oil and how does it look? How does it feel? If the oil is diluted with gasoline don’t re-start it until the oil is changed.

Ignoramous posted an excellent description. I agree with his postulate. Since you’re on a very tight budget, let me suggest an oil pressure check gage (kit) at the parts store, along with a Haynes repair manual. This is an easy test, it’ll be clearly described in the Haynes manual and in the test g…

Any noise accompanying this flashing light? How’s the consumption. We often construct a dinosaur’s head from a pig’s tooth here, so let’s really get the picture a bit more into focus before writing this off. I already know you’re not going to do any internal engine work. You’ll find another beat…

An oil pressure test should be checks of the oil pressure at idle, at 1,000 rpm, at 2,000 rpm, and at 3,000 rpm. YOU could do these checks with a $15 oil pressure test gauge. If the oil pressure is OK at rpms above idle, it shows that the oil pump is up to the task; though, the engine may be rather…

You could buy one of these, change it out, and hope for the best if you don’t want to have an oil pressure test done. This is an easy cheap swap. <a href="http://www.autozone.com/autozone/catalog/parts/partsProduct.jsp?itemIdentifier=123869_0_0_4316%2C5835&skuDescription=Duralast+/+Oil+Pressure+Switch&brandName=Duralast&displayName=Oil+Pressure+Switch&categoryNValue=&sortType=&store=505&isSearchByPartNumber=&fromWhere=&fromString=&counter=1&itemId=134-0&navValue=15300134&filterByKeyWord=&productId=123869&searchText=&categoryDisplayName=External+Engine&parentId=53-0" class="onebox" target="_blank" rel="nofollow noopener">http://www.autozone.com/autozone/catalog/parts/partsProduct.jsp?itemIdentifier=123869_0_0_4316%2C5835&skuDescription=Duralast+/+Oil+Pressure+Switch&brand…

The Auto Zone Web site (of the above link) states that they don’t have the oil pressure switch. Their isn’t a photo, either. Try another store.

Wow! Thanks for the super fast and extremely helpful response. So, I am getting a bad feeling about this whole thing now. Anyway, just to clarify geeaea’s question - No there is no other noise accompanying this light coming on or going off. So far as I can tell there is nothing different about the…

Oil Pressure light comes ON, only when idling

This just means that with 193000 miles tour bearings are worn and at idle the oil flows through them too quickly to maintain enough pressure to keep the light off. As long as the light goes off when you step on the gas you have nothing to worry about, you probably have many more miles in this engine. I wouldn’t however try any top speed runs.
