I have a 1992 SE with the stock KA and I was driving to work yesterday morning, stopped for gas, then got back on the freeway when all of a sudden my check engine light comes on. I pulled over and looked everythign over and it seemed fine so i kept driving and the light would keep coming on then going off. really weird, but the car was running ok. On my lunch break i pull the code from the ecu and its a 34 = knock sensor. So when i drive home now the car wont idle and keeps stalling when i come to a stop. It is also pretty stuggish when accelerating. My question is could all of this be related to the knock sensor? Ive also heard that the CEL wont even come on for the know sensor? but i dont know if this is true. Could it mabey be a bad ground and that is why the ecu thinks the KS is bad and could be the reason for the car stalling? could a clogged/dirty MAF cause all of this? Any help would be great.
thanks
