I have a 1994 Isuzu Pickup with 60k miles on it...Truck runs great, good compression, it does idle a bit high both cold and warm. I'm getting less then 20MPG...Anyone have any thoughts? I thought I remembered my 2.6l trooper got in the 25's what's everyone else getting? TIA <img src="/forums/images/graemlins/cheers.gif" alt="" />
