When going down the road, Mainly in low RPM's, The truck will jerk, buck, and feel like it has lost all power, but it recovers instantly. Some times it does it often, sometimes it wont do it at all. The Plugs and wires are all only about 5 months old. Could it be the tranny? I just changed the fliud in that also. Also ( Dont know if this is realated in anyway) When i fill up on gas, the check gauge light will come on when around a certain RPM (Usually around 2300, not 100% sure because it come on and then goes off so quick). Once i get at a half tank or lower it wont do it. Anyone else experianced any of this?

 

bad fuel pump?

 

when my fuel pump went out, my truck just died, no bucking or anything crazy like that... maybe u got some bad gas? sorry i cant be more help

 

When I slow down and turn the steering wheel at the same time, mine kinda stalls/bucks, but it picks right back up. I just need to fix the idle...it could be IAC?

 

mine does it at idld at a stop light.. if i barely tap the throtle its goes down to 4 or 5 hundy, shakes then goes back up.. unless of cource it dies.. then i gotta start it up again b4 the ppl behind me get pissed off

it doesnt seen to do it any more.. so yeahh
idk i didnt fix it

 

Cant Be Bad Gas. Its Been Going On To Long. Im Thinking Coil Pack Or Dirty Fuel Filter. Could Be The Pump Too I Guess....

 

Check your MAF sensor, fuel pressure, when it bucks do you have the a/c on? Try unplugging your battery for 15 mins and test again.

 

my 94 3.0 does the same thing.. its totally random tho, and only on acceleration, feels like someone shut the key off for half a second then back on again..

 

It will do it when the A/C is off and on. Weird. Cleaned the MAF, Still no help. I'm thinking this fuel pump, or maybe the filter is pretty dirty. The fuel pump to me seam to be louder than it used to. But maybe i'm wrong...

 

i would check the fuel pump. I had some problems and it was fixed with a replacement fuel pump at 30K

 

Mine does it sometimes too, check your fuel filter, if not, check your fuel pump, it turns out on mine the wiring was getting eaten away and the pump was malfunctioning untill I got into the high RPMs and there was more power in the electrical system... Or something like that. All I know is I replaced my fuel pump and the wiring and I was fine.

 

Clean the MAF

 

DPFE is also a possibility...

 

Check out your electrical connections make sure they are good and everything like the alternator and battery. Does it start up all right? You do have that amp drawing power, don't know if you have a capicitor or not, anyway, easy check. My alt fuse went out when I had similar symptoms, but mine died, but can't be your fuse or it wouldn't keep starting up or running I would think, but might be low current.

Just a thought, mabye it will help.........

 

Yeah It Starts Fine. MAF Is Clean. I Wil Probably Change The Fuel Filter This Weekend. This Is Off Topic But Will A Capacitor Help Im Any Way. I Know Nothing Of Them So Am Wondering If I Should Get One....

 

this is probably not the solution but mine did that until the last time i changed my oil and it didnt do it anymore. weird i know but its the truth...

 

did you check the error codes?

Mine exhibits similar behavior when cold and I'm driving w' light throttle at low rpm's: the rpm's will drop, the truck will shake/shudder, then pickup again. The more throttle I give it, the less it'll do it. I got the codes checked, and #63 (throttle position sensor) came up, but they checked the sensor and said it was alright. I might swap out the sensor and see if it makes a difference.

 

it isnt throwing any codes....but i'll see if i can get any pulled. Its weird it hasnt done it since it warmed up outside...But i probably jinxed myself
