my 94 civic d16 spudders on acceleration when warm...generally in second right after changing gears but it does it in all gears as well as an occasional spudder while just revving. i got new plugs and wires, timing adjustment, a new fuel filter, new air filter, oil change...but it still spudders. anybody??

 

How many miles? Might want to consider running some Seafoam through it.

Also, where are you shifting (rpms)?

 

I had a similar problem once and it turned out to be my coil and plug wires.

 

Like tony said, try seafoam, I always try the most inexpensive solution first.

 

Exactly, 90% of the times I've had issues, it was some piddly *** little solution that cured it

 

when are u shifting it is the most inportant and cheapest question. and cause if u go into second at 20 kmph and then shift too 3rd at like 30 kmph your car is gunna shake
