agross91 · Mar 30, 2014

1994 ford ranger 2.3 5 speed 127,xxx ok guys new here but not to the automotive world really looking some help on my daily driver as shes down and i cant commute which is a big deal heres the problem im having. the truck will fire up idle perfect rev up fine but if i try to go down the road up a slight hill or under load it will misfire jerk pretty bad and i will have to press in clutch and feather the throttle until i can get it back running ok to return to idle then it will idle perfect go down the road again it will start sputtering missing and try to die out like its starving for fuel or seems to me. now with that said its normally only taking off or under a load hill etc. ive changed fuel filter,maf,egr,dpfe,iac,egr vacuum solenoid,tps,o2,cat good new correct plugs wires,coil packs have been tested and switched with known good coils there are no vacuum leaks fuel pressure holds 36 idle never drops below fuel pump is only a year old compression good. personally im leaning towards dirty injector or injectors as its running lean this truck sat for about 7 years before it was bought and put back on the highway a couple years ago from a family friend and hasnt had any major issues ill be taking the upper intake off in the morning to check out the injectors and clean them and replace all intake gaskets but wanted a few insights before i do it all or any other ideas

Other ideas: apply punctuation.

Aside from that, the remaining suspects are pretty much injectors or wiring. What codes are you getting from the computer?

No codes from computer. Will not throw a cel unless i unplug a sensor so i know the light is good. Sorry for poor punctuation it's been a long day under a hood

What about a dirty pick up sock on the fuel pump?

If it sat for 7 years maybe the crud starting loosening up and is now plugging up on max suction.

Just a though.

either that or the pump

Fuel psi is good even when it starts acting up and the tanked was cleaned when fuel pump was installed early last year.

Check your spark plugs for fouling, & have your coil packs tested. Run engine in the dark to see if you have any spark tracing on your wires. Clean your MAF. I had the same problems when I bought mine and new c-packs,wires, and plugs fixed it. The previous owner had a lot of deferred maintenance problems. You also may need to replace your throttle position sensor.

Coil packs are good along with plugs and wires and the maf is new. The pcv was good i have got the intake off and injectors are ordered should be here before friday so i should have either a good or bad update. But any other ideas are welcomed!

Sounds like fuel pump - try backing up the hill and see if it's different. (really)

update: the new injectors fixed the truck i appreciate everyones help and input.

This is the same issue I had after I re-did my head, I had two wires backwards the second coil. I would just double check the wires to make sure they are in the correct location. Just because it idles fine doesn't mean anything.
