This an '85 Mustang with a 3.8 L v-6? Thought they only had the carbureted 4 cylinder , and a 302 v-8, possibly throttle body injected?
Check air delivery system, check timing, any trouble codes?

I have 2005 Kia Sportage with a check engine light. No other symptoms. I was told by Kia and Local mechanic that it is the fuel injectors. Error Code states that Fuel injectors are running lean. Put Master airflow- no change. Ran engine test with propane to run rich and trim never changed from 15. Car runs great. Kia dealer said that this is because we use Ethel in gas that it effects the alumium fuel rail delivery to the injectors and that it is necessary to change all of them .Kia Dealer wants $1,000.00 deposit to place order 6 fuel injectors from Kia. (Has anyone heard of that?)Also put fuel injector cleaner in tank.Does anyone have any suggestions before I spend over $1,000.00 to replace all 6 injectors or possible idea of what could be wrong?
