I have a 94 skylark and the engine light keeps coming on.
The cars runs rough and bad gas milage when it comes on.
I paid a dealer to scan the ecm.
They said that the rear 02 sensor was bad.
There is not a rear 02 sensor on this model.
I bought a scanner my self and the code was 13. 02 sensor short or open. I replaced the front (only) 02 sensor. Same problem. I replaced the 02 sensor wire from the ecm to the 02 sensor. Same problem. I replaced the ecm. Same problem. There is nothing else connected to the 02 sensor wire according to the schematic.
I am at a loss for words. I don't know what else to do.
Any help would be great.
