Just put the motor back together after timing bel and head gasket it's running but idles very rough. there is a plug that looks just like the 2 plugs under the diagnostic port but there are both plugged in, now this is on a 91 sedan on my 89 the impulse sensor plugs in underneath the diag port on the side closest to the radiator on this 91 there is no radiator side plug. However there is a wire that looks like it should plug in somewhere around there. I will post a pic soon. It is not the tps plug or afm.
Thanks.
Thanks.
