OK here is the deal...I've had the swap done for almost 8 months now and everything has been great..
However recently I have noticed a hesitation when I am slowly accelerating in any gear...but when I give it more gas, the car accelerates normally..WTF?
I thought it was ignition, so I did a MSD 6A with coil and cap...still there. Then, I changed the wires and plugs, still there.
Then, when I put my ITR intake manifold on, with a new IAC valve, it still did it.
Then I changed my o2 sensor, still there.
I checked the resistance on my injectors, and they check out ok..
The only thing I haven't changed yet is the fuel pump/regulator...
Also I have an Autometer A/F guage and I have noticed when the car hesitates, the A/F guage goes a bit lean then back to rich, lean then back to rich every time it hesitates.
When I give it more throttle, the guage is pinned full rich, and the hesitation goes away.
HELP!

check compression in pistons.

 

Can you say detination, you are not getting enough fuel. Are you running a reprogrammed ECU? If so you probably have a bad fuel curve.

 

I disagree w/ all the other replies, it's not detonation. My car does this same thing... there was a long running thread on it a while back. No fix as of yet, but you might want to check your camshaft timing. I believe elusiveracing23 (on this board) fixed the problem by installing adjustable camshaft sprockets and zeroing the cams... until the sprockets started slipping and it came back.

I just replaced my timing belt with a new Acura part and I haven't experienced the problem since... but I've only driven it for 1 day since then, and I'm already in such a habit of pressing the gas on and off (you'll find it doesn't hesitate if you do this ) that I might not have been testing it fully. When I get my car running again I'll let you know .

P.S. Oh yeah, it's not compression; I did a compression test and ran 220-235 across the board...
