01 4.3 liter, 5 speed. This is my son's car and his mileage is about 6
Any ideas? Also rev sticks between shifting. Thanks,
There you go. Problem in bold. Other than that, on a new vehicle, the oxygen sensors might play a role in your gas mileage problem. How many miles is on the beast?
I'm assuming you mean 4.6 not 4.3. First off, is the check engine light on? If not, when was the fuel filter last changed.....Check all the "tune-up parts" first. Plugs, wires, air filter, fuel filter....if all that is fine, then check the IAC motor and MAF sensor. If it idles high in neutral, it will most likely be the IAC motor(RPM not dropping between shifts is also a common indicator). As far as your MPG, it sounds like a clogged fuel filter. Good luck with it.
