“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

“Car is running Perfect. no issues, no low MPG, no idle issue..nothing at all. its perfect 100% like new . but this fu***n engine light every couple of days is driving me crazy lol. can anyone advise? otherwise i would go to the dealer and flush the Stock tune as i dont see anything i can do after this point.”View original

“PCM? maybe i need to re tune it to stock as i can see the fan initiate at early rpm and the IDLE rpm is high? maybe the previous owner was programming the PCM for specific Octane as i read on some sites if the tune is not fixed this might happen? there is like CAT pop if i rev the car high on stop, i don't think its because of the cats as i know if cats are dead there will be another code.”View original
