1998 Chevrolet Blazer Base 6 Cyl 4.3L


The car accelerates by it self, it will idle down the road at 35mph the air condion clutch will not egage all the time

I cleaned the throttle body, changed the idle air sensor, changed the oxygen sensor and still it accelerates. I feel tht something is wrong electrically since the speed odometer is not correct any more, the magnetic clutch on the air condition does not pull in all the time.

Hey there tecnal,
The oxygen sensor is not related to acceleration, it is an emissions sensor used to regulate the mixture of air and fuel. You need to look at the accelerator cable/ sensor for that condition.
