Hi guys , i am new on this forum so pl excuse any errors.
I have just converted my cedia with a evo6 engine and gearbox. i finished he car and it ran fine , but recently everytime i drive in exactly 1.2 kms the check engine light comes on. if i idle the car for even 40 mins the light doesnt come on. so obviously i tried to scan the car on the MUT III scanner , but it says high data error or no comunication. I even tried with a Launch scanner , but is says no communication. however the power light comes on. This is my first month with an evo if you could call it that so as much information as i hgave couldnt be a waste. I have replaced the oxygen sensor now with a bosch universal sensor 0258 986 507 4 wire.
Please help really dont know what to do ?????????
