Another MPG Q.


2 years ago i bought a really clean extended cab 2.3 5 speed manual with 90 thousand off a girl i know .

Truck needed a clutch so i did that and as i am the kind of person that kikes to get everything over with so i have a reliable vehicle i went ahead and put new plugs and a new timing and serpintine belt along with a new waterpump and idler pulleys all new hoses thinking i would have a good little running truck that would give me good milage.

Ist problem is i have owned and worked on many vehicles in my 30 years of driving and this is thee worst i have ever dealt with far as accessbility.

After all my work the truck seemed gutless and was barely pulling 20mpg in 55mph traffic. My 350 1998 chevy van pulls 18 in the same run.I drive 95 miles roundtrip for my work in 45 to 25 mph traffic so i know exactley what i am getting all the time and i drive very light footed.

Anyways a month later the truck leaves me stranded. Tow it home and put on a ignition module no change no runny.

I come on this site under my old screen name and search and ask and after a weeks of no clues i decided to pull all the injectors and clean them and also put all new plugs with wires and put it all back together.It ran silky smooth right before it died it just had no power and was only pulling 20mpg on a good day.

Put it all together and it fires right up,Only thing i did different is i ran a seperate ground from the ignition module to the battery with the grounds coming off all 4 points of the ignition module.

next i went and bought one new coil because after a week of being on the road it was still a little weak.Put the new coil on and i am getting 29 cosistently at 45 on my round trip.

Now when it died i went through and every sensor and both coils and performanced tested them each 3 or 4 times and everything checked out.

I previously gained a lot of experience trying to track down the bug in my clean 1990 302 bronco that acts up and than runs fine and than dies for no reason to the point that i have parked for over a year again.

Anyways when i cleaned the injectors there was nothing really dirty about them but i cleaned the fine screens in them anyways.

The new plugs i put in i went to stock ford plugs and took the 5 dollar a plugs with 5000 miles on them out.

So other than new plugs and wires and cleaning the filter screens on the injectors i dont know why it decided to run again

My guess is there is grounds leading to all four corners on the ignition module and if that thing in not clean and the block is not well grounded than you are getting bad spark.

My idea for the ground i happened upon on this site somewhere and the person was just as mystified as i am as why it worked.

Also i don t care how well the coils test out go buy a new pair that is what gave me my milage and balls back

Good Luck

I wish my 88 ranger with the 2.3 got 20 mpg, I would be tickled to death.

There is alot of hills and curves here, my truck gets about 20 or so with or without the A/C on. Flareside, 2wd, short bed auto, 225/70/R15's. Recently done a intake silencer and cat delete and haven't computed my mileage yet. Its gotten a best of about 25 since I've owned it. Its fairly comfortable to just hope in and drive though, so I don't complain much.

My '88 S-10 2.5/5-speed with power nothing, and no options, has averaged around 30, and my '86.5 Nissan 4x4 2.4/5-speed got around 20-30 depending on what kind've mood it was in.
