yes but as its not a tech 3 diagnostic computer in Iran we had to do it by an elder version (tech 2) and so its not done copletely and the problem steel runs. please tell me how i can solve it with an alterntive solution if is has.

regards,

farhood

even with tech2 .. you should be getting fault codes inducating where the actual fault lies .. please post fault codes ?

first of all thank you for your attention, i m gonna to check the faults again with tech 2 and inform you as soon as get them.

thanks

as i've checked the fualt again with tech 2 to get the erros code i faund out that it can be related to plugs as the computer mentione d missing wires error for all 4 cylindres. it means the replacement spark plugs dosen's suit engine power.

I would replace the coil pack !

wouldn't be better to replace spark plugs and put a stonger sets instead?

What is the actual fault codes you are getting ?? .. please post with full codes

we've replaced spark plugs with the main ones but the problem is still running and the rpm doesn's exeed 4500 and diagnostic computer (tech 2) mentions error ; missing fire on all 4 cylindres (1,2,3,4) (but not any error code).

Replace the crankshaft position sensor ... did you replace the coil ?? or just spark plugs ??

just replaced the plugs and not coil but i cant check the crankshaft sensor it works properly or not could you please help me to check it?

replace the coil and crankshaft position sensor

i've replaced the coil pack with a new one but position sensor does not match the engine do you have any refrence number or figure of the part?

farhood

we have replaced both coil pack and position sensor but problem still remains and rpm doesn't exeed 4000 could you please help me and tell me what should i do else?

have the cars computer reset .. sounds like it is in limp mode !

how can i reset the computer?

use the tech2 to delete the fault codes .. this reset's the computer to it's default settings ready for a drive cycle !
