I have a 4.2 5 speed 97 flareside with over 200k that is and has been shuttering if i press too far down on the pedal too fast. If i shift at higher rpms i can push the pedal down faster and farther once in in gear. I know this truck well enough to keep it from shuttering whether im trying to really speed up or cruising but is this just the little 4.2 struggling to gitty up or is there a deeper issue. BTW i couldnt tell you exact rpms cause i have the cluster that only has the miles per hour. Maybe its normal and i havent driven enough manual cars to know. SOS haha

 

Sounds like you need new plugs and wires.

Also replace your fuel filter.

I suggest Motorcraft.

 

sparks and wires shouldnt be bad but is the fuel filter cheap/decently easy to get to?

 

thanks manual, ill have to try this tomorrow. if anyone else reading this has a second opinion please post as all ideas and questions are welcome.

 

Fuel filter is under the truck, not too hard to get at, you will need a disconnect tool. Not expensive. Should be changed every 30k.

 

almost positive it hasnt been changed in longer than that so hoping it does the job along with the sparks in wires. Looked up a video, i agree, it should be pretty easy. Thanks for the advice

 

Sorry i didnt get back sooner but getting the fuel line off was the biggest pain in the *** while sparks were a breeze. All in all, no more shutter! Fuel initial helped a little but didnt fully fix it so i went and did sparks and holy cow did it make it difference. Didnt feel the need to change wires yet, but thank you all for your help.
