i live in uk, weather is cold... ive used redex to clean injectors......
from what ive researched it seems to be the MAF or throttle body..........

 

well the MAF is 50$ to replace here in the states if its still under warranty.

 

here in the uk im looking at approx 75 pounds for a MAF and approx 200 pounds for a throttle body...im not sure which to replace...im going to clean the throttle body tomorrow and see what difference it will make....
any idea which will affect idle for approx 10-15 mins / approx 6 miles when battery is disconnected and then reconnected, and which will affect gas mileage the greatest?????????
all your help is really appreciated....
thanks

 

After you reconnect the battery, turn the key part way. do not crank. Wait 3 minutes, then start the engine.
