I'm not exactly sure how to explain, but while driving, my car will jerk slightly during acceleration almost like a fuel cut, during a rolling idle my car will jerk almost as though its bucking from letting the clutch out to fast it constantly does it. During deceleration it will do the same thing and i can't quite figure it out I posted a couple of videos but they're a little quiet.
let me know what you think
thanks casey

I have a 97 5spd and I also just purchased a technosquare ecu for a 96 which turned out to be for an automatic which is why the cel is on, put in roughly a week ago.

this one is light acceleration and then I pushed the clutch in

this one is rolling at idle in first gear (the camera shakes from the jerking)

did it start happening when you put in the technosquare?

 

probably 5 days after is when it started acting wierd, I'm going to put my stock ecu back in and see what happens. This actually happened the day after I put the catback on, but I doubt that would effect it at all

 

How's the MAF?

Are you sure you don't have any other codes?

 

last time I checked the MAF it looked clean and it was recently cleaned about a month ago and I'm getting two codes throwing the CEL since I manually checked it i got 0707 and 0504 which are the a/t and rear o2 sensor which makes sense because its a 96 ecu, but the previous owner still claims it never threw anycodes in his 96 5spd

edit: i just went to autozone to get the codes read and those are infact the only two

 

nobody?
