it's supposed to idle at 700 rpm...this coming from the person who can rip on my sentra

Yea swap out the ECU. We had the same problem 2 weeks ago on on a b16a with a spoon ECU - we put the stock one back in and it fixed the idle problems - try it out goodluck

On mine it was idling low then shutting down, couldnt even drive it.

jesus what do you guys want it to idle at? We had an idle problem with my friend's b16 too. Was idling at like 1500. Swapped the ecu and adjusted it down to about 700-800 and it was running perfect.

your shit was dying idling at 700??? what was it idling at after you swapped ecu?

[Beastiek2]

about a grand. We would put the car in gear and it would stall. We were freakin out. We brought it to the speed shop hea, and they were like yea ECU problem. So they put the stock back in and it worked fine. Beats me.

never had a problem with it dying idling at about 700...weird. We were using a PW0, but I guess it had been messed with, ghetto ebay chip, so we got a PR3, played with the idle screw and shit was running good.

with mine its sputtering a bit when it idles, the tachometer will elivate up and down between 500 and 800 rmp

P2T

that can be a number of problems. Could be your IACV, leaking vacuum lines.

the 99-00 civic si ECU wont help you either, because its supposed to idle between 600 and 800 rpm, if thats the ecu your using, it might be another problem.....maybe its not getting enough gas, or oil, or your timing is probably off.

[Beastiek2]

Is the p28 ECU stock in your car? Just asking I dont kno why that rings a bell .

Yea p2t GSCIVIC7s right for 99 si
