I have 94 integra ls w/ drag gen 3 on it, safc hack, 10 psi.......lately it has been seeming to buck or hitch at part throttle acceleration in cruising gears on the freeway. I f I am cruising in 5th at like 3k rpm and start to lightly start to accelerate it will hitch a couple of times and then start rollin. But if I give full throttle it is fine. It has been doing it more often lately, I don't know if it is that weather has gotten a lot colder lately..like 40s.....any suggestions would be appreciated!

 

i think that's a side effect of the hack. lately mine has been doing that also. pissed me off today it did it a lot more than normal. although cruising on the highway was pretty normal. if that's not normal, i'd like to know how to fix this also

 

It seems to me that if I let it warm up for like 20 mins then drive it or if I have been driving for like a good 45 min it gets a lot smoother

 

... this happens to me too... but i am not running the hack... still stuck with the fmu (i know )

 

It's caused by the splark-plugs not being able to ignite the mixture at the particuliar conditions that are in the cylinder at that boost level and RPM. I'd either buy some better plugs or re-gap them. That's my experience though.

 

sounds logical. i thought of that before. I'm running NGK R5671A-7 plugs with about 0.030 gap. i've been running them for like 3 weeks now. i was running a little rich before. do u think those are fine or get a new set of the same ones or a set of other ones?
