I've been having this problem for awhile now but am running out of ideas. It is most noticeable when I'm going around a turn in 2nd and give it about 1/3 throttle or more to accelerate. The car hesitates for about a second then takes off accordingly. It is also noticeable when taking off moderately and when I shift to 2nd, it will do this a little as well. It's as if the car has slow reflexes. I've replaced the TPS twice now, with the latest unit being a Delco brand. I did check the throttle cable, and it actually feels about right. There may be a small amount of slack, but if I tried to adjust it, it may make the car idle high.

Everything else is fine. Fuel pressure is around 60psi, the o2 sensors (Bosch 13111's) are about 5k miles old, the fuel filter is new, and there are no codes being thrown. Anyone else have this problem?

Have you jacked with the MAF?

Yes I just changed the plugs about 2k miles ago. They're TR-55's gapped at .055". I also haven't messed with the MAF. I know better than to take that screen out.

Anyone else have any problems like this? It's not my imagination by any means, and it can be quite annoying at times as it makes driving the car smoothly but briskly difficult. Could having a ported TB cause any of these hesitations? I'm at a loss at this point.
