“After checking everything the only remain was the PCM. since i dont have spare unit, i went and bought one from the junk yard. Boy oh boy! it was hell to fine one around my area. i had to look in different country to find it at last. it reached me after few weeks but keep it on my room for 3 months (lazy ) before deciding to program it and install it. it fixed all the damn nightmares i had before !”View original

“If it has no resistance, check it for a short to power. If I suspected 02 sensor problems, I would probably unplug those, to see if anything changed when I started it.”View original
