This is weird i just got a P0153 error code on my 98 Mercury Mountaineer V8 5.0. I just cleaned out the IAC 2 days ago with CRC Mass Air Flow Sensor Cleaner and let it dry for hours before i installed it back and everything went back in alright and drove fine after i installed everything back in. However today i put a bottle of the red bottle ISO Heet that has fuel injector cleaner in it today and right after i put it in i took a drive to mix it around in the tank and less than about 4 miles later i got a CEL P0153 cause i scanned the truck with my OBD-II scanner. I cleared the code and took it out for a short ride again the same route i just took when the light came on and it did not come back on. My question is what would of caused the CEL The ISO HEET? Because when i cleaned the IAC 2 days earlier it didn't trigger the CEL. What do you people think doesn't a O2 Sensor CEL Code stay lit until it's replaced? Remember it turned on right after i put the ISO HEET into the gas tank and it took for a ride less than 4 miles after i put the bottle in and i was able to turn the light off and it didn't come back on after i cleared it and went back for another quick ride. Thanks
