This has been a problem i've been dealing with lately its been real annoying, it seems that everytime i go through all the RPM's without boosting theres no jerking hesistation or anything, but when i'm around 3400-4000 and i give the car a lil boost it starts to hesistate a little like stop real quick and keep going and do it again before it reaches 4k. But if i go WOT theres no problems really, could these problems be due to my clutch going out or what? I have no idea what it could be, it can't be secondaries because it would be hesistating under WOT and when i'm not boosting, and it doesn't really sound like grounds but you guys tell me.

Ok... So if you go WOT, you have no problems right? The problem is only at partial throttle?

I'd say it could either be the TPS or maybe a grounding issue. If I were you I'd check/reset my TPS and clean-up the grounds.

I had a similar issue from 3k-4k RPM's only under partial throttle and at *most* light boost (like 2-3lbs), if I gave it any more throttle everything would be smooth. I attributed the problem to my failing TPS. My narrow-band A/F gauge would start fluctuating from lean to rich, lean to rich--just back and forth until the secondaries kicked in. Only under partial throttle.

man im having this same ******* problem, i just got my tranny back together and went for a drive, when im at light throttle, at about 3500-4k i get a werid hesitation, but when i mash it, its all good.

That weird hesitation is probably bad secondary injector grounds (or something of the sort).

Search for "3800 RPM hesitation" and you'll get reading for days.

but when i WOT its all good, arent the secondaries kickin at WOT?

i used to get this problem, it would mostly come on a hill, id be at mid throttle and it would keep hesitating back and forth and wouldnt accelerate unless i give it like 3/4 throttle or more.
