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

I know it's been years but I remembered that I didn't update this thread with the solution.

________________________________________________


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).

I did a full ignition tune up and no difference.

And I'm running the P28 that came with it.

Your TPS could be acting up, and causing your engine to pull incorrect timing, resulting in you losing power at strange times. My $.02, as I am looking into similar problems.

I am wondering if it is a intermittent TPS problem. I'll test it soon. Thanks

Don't know, could be. I will say that this motor pulls real strong through the midrange though. Don't know if the WS exhaust would be the cause.
