^^ cheers guys i just hope it fixes my fuel ecconomy problems. I have cleaned the AFMs and am running a batch of injector cleaner through the fuel. I did a test that is specified in the engine manual i have and tested the resistance of the sensors, the manual said they should be about 2.6 ohms but i got readings of 3.8 and 3.9 ohms does this mean they are stuffed? I have also heard that the charcoal canister can cause fuel consumption problems, is there a way to check to see if it is functioning properly?
