hi guys, i need to go for emission test soon, and i did everything i could..

i had lots of sensors bad,

knock sensor replaced.

4th gear problem fixed and some more..

well here is the problem..

i have EVAP sensor

and air flow..

when i reset the ECU EVAP is gone. but airflow is up..

i drive for a week. come back to mechanic EVAP is up, air flow is down..

he dosent know what the hel is it.

i was thinking i need new ECU?

any suggestions?

 

Any codes?

 

I suggest a new mechanic. If he cant diagnose the problem then take it some where else.

 

EVAP code is left and Air flow code.

but i think he is ok, alot of people recommneded.

 

Post up the codes search in the sticky section for the codes it will tell you the problem
