Question about 1994 Toyota Pickup
I can hear the miss at the exhaust but can't notice it so much under the hood. jumped the diagnosis terminals under the hood and the code thrown is 2, 4, 3, 1 (2 flashes, 4 flashes, 3 flashes, 1 flash). I've changed the plugs and wires and mass air flow sensor. I started having this issue the day after the last time I got gas and haven't driven it since. any help? thanks
I believe you have two separate codes; 24 and 31. 24 is "open or short in intake air temp sensor circuit" and 31 is "open or short in airflow sensor circuit at idle". These sensors may share a common ground so I would check that as well. You could also try putting a stethascope or (long screwdriver with your ear at the other end) to each injector and see if all are clicking like they should.
