My ranger is basic, no air, no powered windows or mirrors. I have been experenceing bad fuel mileage as in 6 mpg. I may start another discussion about this but it may be due to back pressure. The head gaskets have been redone. So any info on a comptuer reflash maybe to a 93 oct performance would be sweet. I have a obd 1 plug.

A reflash isn't going to do anything, and you wouldn't want to run 93 in any rangers. Maybe take your Ranger to a tuner and it will get better mpgs and power.

Reflashing your ecu is possible, but that may not be the problem. What other tests have you had done? Plus 93 octane really doesn't do much of anything. That's basically there for imports, and cars that run a higher compression ratio than normal which you'll find on alot of higher end sports cars and heavily modified engines.

93 octane wont do anything for a ranger reflasing the ecu on an obd 1 wont help ether try a general tune up a vacu flush top end cleaning fuel injector cleaning if you have them air filter and throtle body cleaning. 6 mpg is a major issue that cant be fixed by simply switching octane or reflasing. i had the same problem when i bought my ranger i did a full tune up on it and my mpg went way up.

Well first I get more mpg out of 93 for some reason, I'm still on my tank of it when the store ran out of 87 so they had to sell 93 for the price of it. I usualy get a week out of my tank, to and from school and the station (2.5mi max).Throttle body has been cleaned, maf has been replace twice even when the old was good, my exaust is like a puff puff when you put your hand over it. If you catch it at the right time, have your and on the wheel you can see my arm shake. On a scale 1-10 10 being extreme shaking I would say it's a 2 or 1. I have to put the pedal down harder to make up for the performance. I ran it on the interstate hard pusing 70-75 and I got 14 mpg supriseingly Please note this motor was droped in with 80,000 miles and later found out it had a blown head gasket. I am a volunteer fire fighter and I really need the performance. On a cold day (25deg F) I would start it before I leave for school sometimes hear a small tic/pec but nothing needing to turn the motor off. My dad is a full mechanic and share most of his traits but he doesn't want to do anything with it. If I am able to make a video of it I will share a link. Thanks in advance.

You have an oil flow problem. That tic you hear usually means that valve train isn't getting enough oil for some reason. Check your engine oil and look around for any puddles of oil. My truck done the exact same thing yours was doing and it turned out that the rear main seal was busted. If it's consuming alot of oil, there could be a piston ring problem or a busted rear main seal. As far as the shaking goes, Ford rangers usually do that over time. However the place that built your engine could've bored the block wrong.

Thank you for the reply. My motor underneath is farely clean except for the trans from the last motor. It keeps oil good haven't added any in it. It has aftermarket engine heads on it soo.... it may be another cause. Any possible chance the timing could be off a hair?

how many miles are on the motor if its stock compression 93 should do nothing for you. thats all an octeane rateing is is ressestance to detination.

Around 80,000 mile motor was dropped in, truck itself has 159,000. Im just now on week 3 of 93 oct just under half a tank with 107 miles.

Have you checked the engine compression? It can tell you a lot about the condition of the rings, seals and head gasket. If something is causing it to be to low, it can cause reduced performance and increased fuel consumption.

Do you know if the CAT. has been replace? I f it hasn't since 2002 it maybe your problem. They will get blocked up and cause exhaust back pressure and there go's your mileage. 93 octane will only push your mileage further south.

Simplicity is the ultimate sophistication.

Torque it down till it breaks off, then back it off 1/4 turn.

My bad for the late reply. I did find a problem. The gas tank filler hose was cracked where the elbow goes into the tank. It has been replaced, I had to take the bed off to do it. I do not think its compression at all but back pressure. Ik no history of the truck, it was purchased for 650 w/blown head gaskets already apart. It was weathered on engine block and decided to replace the block. Had 159,000. I just recently filled it up the day after I fixed the gas smell I been getting when I had the back glass open going down the road. Put 87 in it for a full test to see how this goes. It almost feels like the cat may be stopped up. Have put my hand over the tail pipe and its like puff puff and hear a little misfire. Let me see how this goes with the new gas spout, evac system may have not been working its full process giving me bad mpg.
