94 wrangler:rough idle, now no spark
I have a 94 yj 4 cylinder and in the begining of my problems it was having a rough idle and I would have to give it gas until it warmed up but after it warmed up it would cut off and then would not start back up right away. The codes that it put out were: 12, 33, 23, 24. I have replaced or checked the following: o2 sensor, fuel pressure regulator, map sesnor, mat sensor, throttle position sensor. Not sure what to check out next, thinking the crankshaft sensor or the ecm. Thanks for the help.
