I never had this problem on my 93 Base, but seem to be having it every now and then with my 93 R-1. I tried doing a quick search for this topic and turned up nothing. Can someone tell me an easy fix for this problem?? Thanks!

Well, I don't know if there really is a fix... But from what I hear..



Try beefing up the engine grounds. They say that works.

The only sure fire way I know to elminate the 3k hesitaion problem is to relpace the ECU with a stand anlone like the Haltec or Tec III

. Or install the Apexi power FC.

Improving on grounds will not eliminate it.

grounding will not eliminate it....i can attest to that. i have about 20' of 8 guage wire that i added to and replaced many weak link grounds, and i still get it. however, through this winter, and me driving the fd every day, i have noticed it more than ever. it seems like it is more exaggerated when the car is still warming up, and has not *fully* come to temp.....[NO I AM NOT GETTING ON IT WHILE COLD] however, mine seems to be more apparent between 3200 and 4k...i just depends. oh, an di normally feel it in 2nd and 3rd gear....

why dont you just go non-sequential? Will definately eliminate 3k hesitation and only costs about $5 and you can use your stock ecu!!!

i have been NS for almost 1 year now, but it only eliminates the 4500rpm transition....not the 3K hesitation....which is electrically or fuel related....

it's spark related,and no amount of extr grounds will help, I tried it all, even grounfing the ecu chassis. Get a Power FC It was the best investment I ever made, besides the car itself!
