I have 1987 Ranger V-6, Truck starts, but misses, sputters, etc. It will drive, but it bucks, misses, jerks, till I get it revving high in gear. Rides along and then acts like it's out of gas, sputters, and then takes off again. ??

When was the last time you changed the fuel filter. My Ford has same problem an it was a fuel filter.

My work truck run great until you put it in gear it would die it jerked hard in reverse like it was missing . And it was the shift telay

I am curious to know what the scan told you when you originally checked it? A lot of people spend way more money than they should changing parts and guessing at the fix. Tell me a little more about the what the scan results.

I have seen this problem and it is very often a problem with the engine wiring harness, where that may lie is anyones guess, look at places where the harness moves around allot.

I think that you need to be more specific when you say that you have changed everything... Because i'm sure that there is MUCH more that has to do with this problem then you may think.... Has the fuel pump fuel pump float pressure regulator and filter been changed out. Also has the crank sensor been changed out. What you the cam sensor?

Sounds like leak in high pressure side of turbo to inlet manifold tube.
Results in gutless or no performance but idle & revving in neutral ok.
Check for splits or loosened joints.

Yes (low pressure) one sit on the inner frame rail on the driver side under the truck by drivers door.High pressure is in the gas tank, if you are going to replace fuel pump, don't forget fuel filter.

Depending on youre mechanical ability you can spend 20 bucks for a rebuild kit on your carburator.

There tends to be many different potential issues with youre description of the problem. My best advice for you at this time, would be get the carburator re-built and check youre fuel pump/fuel filter.

But you can always go to youre local shop and get a free estimate.

you can try shifting it manualy,which will eliminate the shift modulator,if it works you are in business..although it sounds more like not enough fluid in it,check the level warm,if you are more than 1 quart low it will act like that.

I'm having the same problem with my 90 2.3L Ranger. I replaced the EGR Valve back in August and the truck ran fine (but the gas mileage was bad) until late December . I knew it needed an O2 Sensor back in August but didn't replace it until last Saturday along with the Idle Air Control Valve, Plugs and Wires. The truck ran fine for a couple minutes then started running like a VW bug! My code reader is now throwing out an EGR failure code, so I guess i'll take the 4 month EGR back and get a new one, and see what that does!
