I guess its not so much a back fire but bad misfire. will not go up a hill keeps lurching ahead under the misfire...


Often it takes a load to bring out the misfire like hard acceleration or climbing a hill, did you check the spark plug boots on the coils for signs of burning or other damage of any kind.

I get s flat spot upon stepping on the accelerator, it is petrol engine and has a carburetor(no its EFI)


it has no CARB,
carbs ended here in 1994

scan the pcm ! first.
it will tell you , the reason.
the errors from the Trottle body or the 4 TPS sensors
2 in TB body motor.
2 under rigth foot
if 1 disagrees, PCM goes to limphome and is weak power.


you can NOT fix or diagnose any modern car
lacking a scan tool.

you cant.
hesitation is misfire
and has over 50 causes.

why would I guess.
I won't'
scan it and tell us the bad news.

96 Ford Explorer is studdering (misfiring) when going up hills


I have the same exact problem that just started immediately AFTER I got a tranny service where they changed the Trans Fluid, Trans Filter, Fuel Filter. Took it back and they say nothing is wrong with it. Took it to the dealer thinking I could get some REAL answers... they just told me to replace spark plugs, wiring & coil, for $900. Only studders when quickly accelerating above 40mph. I've check other forums, they say to clean the Mass Air Flow sensor. Haven't tried it yet. This seems the easiest before replacing spark plugs. Any other suggestions anyone?? Please.....

Sounds like a timming issue. Have you done a tune up? If so I'ld have someone check your timing. If not, do a simple tune up first to eliminate the possibilties of misfires.
