engine sputtering
This only seems to happen when im in 4th/5th gear, i'll be going along continuing to get up to speed, and it will just cut off, like the fuel is being cut off for a 1sec at a time. I'm thinking bad fuel filter, or fuel pump isnt pumping fast enough or something? I just got done running seafoam and cleaning out the injectors and such too. Any ideas?
Thanks.
p.s. - it only really seems to do this while im still gaining speed, not when im coastin down the highway doing 75.. just getting to 75 is the issue.

yeah, i was thinking the filter too, but why would it only do it in 4/5th gear while gaining speed, and its usually right after i shift to the upper gear, it kinda sputters a few times. it might have happened in 3rd a couple times, but definitely way more in 4/5th..

I gotta think that's it's MORE than a coincidence that this happened after the Seafoam. Were you having problems BEFORE the Seafoam, and that's why you put it in? Or were you just doing your regulr maintenance and trying to up the gas mileage and throttle response? Was this the first time Seafoam has ever been through your ride?
You might want to go systematic with your checking and start simple with pulling a plug to check for fouling. You can pull the O2 sensor out of the Cat and hit it with some steel wool. Sometimes they can foul out.
Just a few easy things to check before you get all involved with pulling things apart.
Good- luck and always look for the easy stuff first-

You might also want to think about pulling off the air filter (if it's nice out)and drivin it like that to see if the air is being restricted. Of course, I stress, no dirt roads or rainy days.
Again-
Good-luck
