I changed the plugs, rotor, distributor, fuel filter, spark plug wires. Disconnected the egr to see if helped....But I noticed that it only stalls when the air temperature is hot or humid. Never in the morning or evening...I'm thinking this might be the oxygen sensor...help
91 gmc jimmy stalls at idle to acceleration...Oxygen sensor?
No, prolly not an O2 sensor.
Since it seems to be temperature related think other electronics - ignition module, coil... possibly the fuel pump...
