gas eater

[Slushie12]

I have a 94 standard cab with a straight 4 and a manual transmition. I took a trip recently and clocked its gas mileage at 18 miles per gallon highway... that seems a little low to me for a 4 cylinder engine on a light truck. Any suggestions? I've been having problems with my fuel line not getting the gas to my engine when in idle... could that be it?

Is your fuel delivery problem due to a clogged fuel filter?
-change fuel filter
-properly inflate your tires
-use cruise control
-turn off your a/c
-remove excess weight (bed full of junk?)
-drop the tailgate/use tailgate net
-new spark plugs/regap plugs
...and my two favorites, which cannot be overlooked because I've seen people do it...
-keep your foot off the brake while driving
-"OD" means 5th gear, use it on the hi-way.

I had the same Question, about two weeks ago. Mine is a 94 extended cab 2.3 5speed manual. It was my daughters truck, and I was getting 19 if I drove light footed with out air around town.

Last week, after a knuckle beating 1 1/2 hour 8 spark plug change (yes two per cylinder!) and plug wires, my last two tanks averaged about 22 miles per gallon around town and highway. I should tell you, that I had a light irregular miss before I started. Poor idle. Also no power when I turned on the AC. Seemed like I always had it floored to flow in traffic. It wound out the the spark plug gaps had greatly increased over the years and I was getting a week spark. The fellow my daughter bought it from last year said it was well kept up. I bet they were original or second set with 120k miles on the car.

I was looking for an aid for hourse power increase of 10 to 20 at rear wheel when I saw your question. Maybe a computrer chip or header. Any recommondations from some one?

my Ranger (4 cyl) got 25 mpg before a $200 tune-up .....now it gets 27 mpg ..... I only use Shell gas & once a month use Marvel Mystery Oil in gas

Before buying any anything, I would buy a fuel pressure tester. It's a good addition to the tool box, and it's the only way you'll be able to rule out fuel delivery problems. ....unless you just start throwing parts at it that you probably don't need and spending time replacing things that don't need replaced... I would check the fuel pressure regulator. Check for fuel in the vacuum line. (If so it's toast.)
