I just swapped out engines in my 1995 nissan altima and now the check engine light is on?
I ran the diagnostic check and it shows three codes. One is for the mass air flow sensor, one for the knock sensor and the last is the revolution sensor. These were all fine prior to the engine swap. I have changed the mass air flow and the revolution sensors and still get the same codes when I run the diagnostic. Could this be caused by a bad or missing ground wire?
have the same problem?
