Two things come to mind. O2 sensor or a tps sensor. You really need a code reader to know exactly whats going on. You can replace every sensor on the truck and still have a problem.
An engine cylinder misfire has been detected
Go to AutoZone and ask one of the fellas to come out and "check your check engine light code". They will be able to tell you what the problem code is, as well as re-set your check engine light.
probablly not getting fuel check your fuel filter unless timing is off
The 93 Caprice could be losing fuel pressure. Check the fuel filter and the pressure to see if the pump could be bad.

If the check engine light is on for your 1991 Toyota Cressida, that makes that some repairs need to be made to the engine. Taking the car to a certified mechanic to perform a diagnostic test can confirm if there is any issues with the engine.
It could be a # of things, You need to have the engine scaned with a engine scanner. Some parts stores will do that for free.

No, a loose gas cap can cause the check engine light to come on but not the low fuel light.
Idle control valve - a part that costs about $200.
Disconnect the negative battery cable for a couple of minutes, then reconnect. This will erase the codes in the computer that makes the CHECK ENGINE light come on. If everything is okay, the CHECK ENGINE will stay off. Tried exactly that advice on my 2001 Camry....and it worked like a charm!!!
Have vehicle scanned to determine the problem - most auto parts stores do this free
