feels like a 25 hot of NOS

[68Malibu]

Supposed to be "hit". Anyway, I have a '99 5 spd and when lightly accelerating in 1st and 2nd gears, around 2,800 rpm, the engine suddenly gets a big shot of power. Like I just stabbed the throttle. LIkely does it in all gears but 1st and 2nd are low and thus one would feel such things more. Been doing this since I bought it a year ago. Any ideas?

V6 or 4 cylinder?


Also, what part of NC?

I feel that on my 5spd. I think that is where the powerband starts to appear

4 (great on gas but little power).

I am a few miles E of Raleigh


Yes, I figured it may be where the powerband kicks in as I have felt that on many V-8 engines I've built. Only this is so dramatic at such little throttle opening. The V-8s did not show it much unless you had your foot in it at least half way. Maybe just a combo of the manual trans and a small engine.

the 5SFE doesnt have any section in the powerband where it jumps up enough for you to feel like youre sprayin nitrous, thats for sure

[68Malibu]

Do these engines have an IAC (idle air control motor)?

I know on some cars a crappy TPS can cause this problem.

[CamryPunk]

It's your Vtec.

[Venom_5]

either that, or you have enough nitrous to blow up a city block!

The floor pan might fall out too...

The 5S-FE hits its peak torque at about 4400 RPM.

I dunno, maybe that 2800 RPM is about the moment when your clutch is fully engaged.
