using the 99-00 dx harness
d16y8 motor
i moved pin b6 to b23, unhooked b15 for the IACV
wired vtec correctly

VTEC will not engage, idle is not right, rev limit at 6800
NO CEL's WTF?????

any ideas?

poison

I thought you were throwing IACV code?

Timmay

i was but i reset the ecu and checked all my wires.
now i have no codes at all but still no vtec or a good idle

poison

Best thing to do Timmay is grab a digital multimeter and test the wires for vtec between B12 (VTS), C3 (knock) and C10 (VTM).

And you know about oil pressure deal. Make sure it's up there.

How does it idle? Wavy, rough?

Timmay

oil is right on the money, vtec is wired right

idle wants to idle high then low, like if you rev it then let off it will drop down to 1k then right back up to 1.5k then slowly back down to like 900.

ahhhhhhh i hate problems

Timmay

i wonder if it matters what plug i use on the IACV? i just grapped a plug from another harness that fit on it

Timmay

helppppppp

Katman

what ecu are you using?

as long as the IACV plug is round style and you color matched up the wires and spliced them together, the IACV shouldn't complain...

Timmay

using 99-00 P2P
i just used a plug that fit on the iacv, the colors didnt match to the 99-00 dx harness
i did all the pinning right, i even tried switching the 2 wires on the iacv

but how come im not getting vtec and the idle sucks but no CEL's

money's nice. I need some.

Timmay

this sucks, i want this car to run right

EE_Chris

Unplug the IACV; What happens to the idle?

poison

He was able to get the car to idle fine after putting the coolant lines to the iacv, but vtec I guess still won't go and rev limit is 6800.

He'll be here to explain more

Timmay

NO VTEC, NO CEL's ahhhhhhhh its killing me

Great explanation

Now, is poison right or do you have a messed up idle?

Timmay

im out of ideas

EE_Chris

Me and you both...
