Hey, couldnt find a thread on this so time for a new one.
Recently I've been having issues with the car bucking at both low and high speeds. It really only happens when I am accelerating though and it gets worse if I really lay into it. It doesn't happen every time but its annoying when it does.

Ideas? I'm guessing fuel pump is going... But it only bucks around corners

When you say "Bucking," you mean the engine cuts in and out while accelerating? Does it make a difference how much fuel is in your tank?

There's a 4 page thread plus some on this topic by the way lol, I searched for "fuel pump" and "bucking"

It helps to use google to search the site as well with the "site:rx8club.com: insert topic here" though I just used the bar at the top to find that one

Yeah I looked into that. Its probably not fuel starvation it also happens on a full tank of gas and I mean just topped up. . The P0102 code is coming up almost daily now Ive cleaned the connections and the sensor, so its either the MAF or the harness :/. Do you think a vac leak could also cause this?. Bucking as in the engine will surge quickly almost like you give the car WOT and then cut it and repeat 4-5 times.


First post was supposed to say accelerating through a corner* It doesn't happen in a straight line. Even if I get the back wheels spinning, an jerk the car around. Only when exiting corners.
