Over the last few days, and after a recent oil change my 2001, RWD, 3.0L, 5 speed manual Ford ranger has started jerking/bucking when accelerating. It happens in every gear whenever I go past 1/3 maybe 1/2 throttle. No evidence of clutch slipping, no loss of power, no engine lights on, smooth idle... It almost feels like its not getting fuel in a pulse pattern
Any ideas oppos?

Had this happen to mom’s old 2000 Civic once when she had it and her 2010 Accent sedan once - turned out to be the coil-on-plug packs in both cases...?

Has the fuel filter been replaced lately?

Fuel filter or fuel pump?

How old are your plugs/wires? Fuel filter?
Does engine load matter? As in if you free rev it does it buck, or only under engine load? Better or worse going up hills?

Not sure I bought the truck in May with 61k on the clock almost 65k now. My guess is that all of the above are old. I’m going to check the plugs first. Just waiting for it to cool down.
Free rev is fine, only under load.
I’d say slightly worse but not much up hills.

I’m not sure as I’ve only had the truck a few months, but most likely not.

On my list to check, starting with plugs.

Since a fuel filter would be good preventive maintenance even if it’s not the problem I would probably put that on the short list of things to start with.

Simplest thing I can think is fuel filter, Could also be bad plug wires or a coil that’s failed and can’t keep up with the higher voltage demand under load. How long has it been since spark plugs and or wires? If the plugs are ancient they will require more voltage to arc and this will tax the ignition system eventually leading to a screwed up coil or even ignitor. But these things would lead to a loss of power at least momentarily (though that could cause bucking)

Plugs, wires, and a fuel filter first. JMO.

Could be ancient I’ve only had the truck for a few months, thanks for the tips. I’m going to check the plugs first as soon as it cools down

Sounds very much like a fuel filter - if you’re lucky.

I can confirm - on Hondas and Toyotas it’s almost always coil packs going/gone bad. I can’t say about Rangers, mine is still going (‘07 2.3L)
