OBD Codes P0100 and P0110
Drove my 96 HB (109k miles) today to pick up my daughter from school, ran fine. Came back out and started the truck, pulled away and it started to die on me.
Baby'd it back home and replaced the following: plugs, Dist cap & rotor, wires, and fuel filter. Have the PCV valve, but can't find it on the intake manifold - any help?
Took it for a test drive and it started acting up again after only a few hundred feet. Gets up to about 3k RPM and the starts spitting and sputtering. If I let it sit and idle it will idle smooth for 5 mins and the start fluctuating.
My scanner tells me the 2 codes are registered P0100 (Mass air flow Sensor circuit) and P0110 (air temp circuit).
Anybody have any ideas what might be causing this? The air flow sensor and air temp sensor are both mounted on the intake/air cleaner assy. Both of these are connected, but I don't know how to test them to ensure they are working properly.
Is there something common between these two sensors that may be causing the problems? My scanner is registering readings from both sensors.
Thanks - Ray
