1994 mazda b3000. 3.0 V6
Normal idle 600-700, occasionally will idle up to about 1200 for about 3 seconds and then down to normal. I Also noticed when coming to a stop, engine RPM stay at about 1000 and come down to normal range within a few seconds. Also idling a little rough. Replaced Plugs@.044, cap/rotor, wires, coil, air cleaner. Possible dirty MAF? EGR? IAC valve? No error codes.
have the same problem?
