UPDATE: Checked ignition timing and it was off. Set it correctly and the B16 runs perfect with no dead spot.




My B16A acts strange sometimes. It has kind of a dead or weak spot when accelerating from about 2900rpm up. It usually happens in 3rd, 4th and 5th gear, and I think I simply don't notice it in 1st and 2nd because it revs so quick. Like I said, it doesn't happen every time I drive it, sometimes it'll go weeks with no problem. Makes me think it's something electrical as opposed to a vacuum leak or a lean spot. It is bone stock except for a real cold air intake box and the original WS exhaust system. It runs nice (minus the dead spot) and somehow gets 36+/- mpg (no lie).

check your a/f ratio while looking at your upstream o2 signal

do you have a leak ? like what i mean is, i have a leak from my header to my downpipe and it causes a power loss when im at those same rpms in those same gears. IDK just a guess

I do have an exhaust leak, that might be it. I f@&king hate working on exhaust.
