Question about 1992 Toyota Corolla
Did a compression check on all 4 cylinders and received a reading of about 50 PSI on all of them.
All 4 cylinders are at 50 psi?did you remove all of the spark plugs to do a compression test?do you have a quality compression gauge ?do you have the right fitting installed in the spark plug hole, and is it tight?
if so. your next step is to preform a cylinder leak down test. you will need an air compressor to so so.one of the best things about your toyota is that it is a non interference engine. which means if the timing belt jumped, you wont damage any valves. be sure to check you timing marks before you decide to just junk the car.you could have some bad valves, or just need new rings!definetly keep searching before you junk the car!start by checking the timing, and then do the leak down test.

burned valve is likely the culprit.... or bad rings.... hook air up to that cyclinder one at a time.... and listen where the air is escaping... be aware that the motor will rotate till the piston is at the bottom of it's rotation. if it's a burned valve you will have to remove the head and replace it but somewhat easier job then replacing the rings. darn almost forgot.... it can also be a blown head gasket.... same procedure but you might need a brush and some soap water to test for an air leak at the side of the head. when you are done spray some wd 40 on it to get the water off so the spark plugs do not arc.

Per the Ford manual, the acceptable range is 155-195 PSI. It sounds to me like you don't have a compression issue with this engine (without knowing the exact readings for each cylinder). Normally one cylinder being higher than the others, but still within spec, would not concern me a lot. Had one been much lower, then I think that might be cause for concern. There could be many reasons for the one hole being higher. If the engine hasn't been rebuilt in a long time, there could be carbon deposits in the compression chamber. There are many chemical fixes for this availble at your local parts store. If the engine is running fine with no pinging or detonation, I'd just continue to enjoy your classic ride (I own a 1971 Challenger converitble with a 440-6 pack, so I understand the joy of a classic car!).
Good luck and please let me know if this helps!

Mass Air Flow sensor! Just remove your air filter cover. Go to Auto Zone and purchase some solvent. Spray past the air filter and it should correct the problem. If not, replace the Mass air-flow sensor. This is commonly mistaken for an oxygen sensor. Mine did this and I followed these steps and it fixed the light. BTW, the light stayed on for 5 years before I fixed it. Never hurt anything. It's normally something to do with emissions. Dummy lights. :)

You can do this one yourself if you want it does not require removing the steering wheel. just the plastic housing from the steering column.
remove housing/cover. then look at housing with cylinder lock assem. on bottom about 1.2 inches or so from the end of the lock assembly you will see a very small hole insert metal pin into hole and push in while turning the key in the ignition backwards to accessory positionyou will feel the pin your pushing move in a bit, then you should be able to pull the cylinder assembly out. insert new assembly with key in the same position and turn forward this will install your new assemlby then reassemble your plastic column covers.

Tips for a great answer:
1,226 kPa (12.5 kgf/cm2, 178 psi) or more
Minimum pressure: 981 kPa (10.0 kgf/cm2, 142 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm2, 14 psi) or less
