My 03 v6 suddenly started hunting at idle after it gets warmed up. It goes from 700 to 4000 and back several times a minute. I removed the air filter housing and looked all over for a vacuum leak, fuel leak stray wiring anything out of the ordinary and can't find it. In desperation I ordered a new Maf. It isn't throwing any fault codes either.
Help Please.
I replaced the MAF to no avail so I'm now thinking of the Throttle body. I took it off and cleaned it and all the sensors but it only seemed to make it worse???
