On my 94 I have pulled up two trouble codes, 1150 and 1151. I know these are O2 sensor codes but which two sensors? I have an H-pipe without cats and the MIL eliminators on the back two. Could this eliminator be the problem? My car Idles rough after it warms up and at part throttle it misses and surges real bad but at WOT it runs great. PLZ Help??

 

Just went through my code book and my mitchell 1 and there are no trouble codes that high for an OBD 1 car. Are you sure of the codes? This is a 94 Mustang not a truck or something else right? The highest code number I could find was in the 900's. Get back to me with you find.[8D]

 

Actually my 94 has OBD 2. That's probably why you only go into the 900's

 

Not naturally it didn't. OBD2 wasn't out till 96. SO if it is OBD2 what did it come out of? The codes for OBD2 are all P then numbers. So give me some more info and I will try to help. [8D]

 

So have you fixed you issures? Just checking. [8D]
