Default Throttle LAG at WOT under 2.5K RPM

i feel the car bloging, draging at WOT under 2.5K RPM can this be related to throttle cable. Just started happening recently BTW.

Is it a bit of hesitation right when you get on the gas? Cuz thats what mine is doing too and I've been meaning to ask about it.

It's because we have no power down there. Keep it above 3k.

haha - no, that isn't it. I haven't actually checked the rpms when I get the little stutter, so for me it could be at higher rpms, too. My 2000 didn't do it.

She's going in for a visit to the mechanic anyways; I haven't had it checked out since it came up from the states so i'll cross my fingers and hope they know whats going on.

This happened to my S2000. It was the fuel injectors. I went back to stock and never had the problem again.

How many of you guys have modified fuel injectors?

Here is something I found if you want to adjust the cable and see what happens.


requires 2 people:

press accelerator all the way to the floor
while accelerator pedal is pushed all the way to the floor, see if you can move the throttle anymore by pressing on it wiht your finger. if it won't open anymore, you are ok. take foot off of throttle and then press throttle cable with your finter at the throttle. should only be about 1/2 inch of slack in the cable.


If you think that is what it is. Try this or give this to the mechanic to adjust for you.
