My 1990 Toyota 4runner won’t stay running after I changed the air filter. Starts up for couple sec then dies. It ran the same morning then had problem after changing filter.

Check to see if you disconnected a vacuum hose, or if you disconnected the wires leading to the Mass Air Flow sensor (MAF)–assuming that a vehicle this old has a MAF.

I did put a fuel injector cleaner in the tank, could it have put a clog into my fuel line?
