I have a 1988 GMC S15, my service engine soon light comes on, I noticed that my 02 oxygen sensor is unhooked under the hood, i had replaced the spark plugs the other day thinking that that'll cure the problem but they didnt, so then i been told that it is the oxygen sensor, imma try and plug it up and see if it'll still work before i get a new one, its a 1 wire type sensor, cause sometimes I sure noticed poor acceleration, hesitation, rough idling and stalling, so that got to be the problem after reading alot of these questions from consumers on here, when i hook it up, would i have to unhook the battery for the code to erase off the computer in my old model GMC truck.
