ok heres the problem, had a few vac. leaks and took care of those, so i have no vac. leaks now, car cold idles fine right at 2k, but when it is warm and the idle drops it just dies... tried to get it to idle using the screw but i have to turn it ALL the way out to get it to idle at like 200 sometimes it throws a code 14 (iacv) and sometimes not, i switched it with another good known working ecu and it did the same thing (minus the cel, but i didnt want to run it too long since i was running my b16 off a p05 lol)...

car cold idles fine, but when the idle drops to what should be normal, it jsut dies, ive already screwed in the fitv all the way and cleaned it so im sure its not that(ive even bypassed it to see what would happen, and same problem only with a messed up cold idle)...

anyone have any ideas?

iacv is getting 6v of power, havent tested the tps but the map is ok i switched it out for a known good one and it was good...

im running the CX fuel pump so iono if that matters, i know its not good, but jus checking, plugs did look a little lean...

compression test was 195 all the way across on a hot engine with throttle wide

heres my setup if its necessary:

1992 cx hatch
jdm 2nd gen b16a
aebs intake manifold
cold air intake
ractive header and full 2.25" exhaust with no cat
pr4 ecu converted to p28 socketed and chipped with p30 maps by j-ktuning

any help would rule, at this point i am now removing the whole intake mani again and cleaning everything and replacing gaskets and whatever needs to be done, someone help i need to find out whats up with this

have you tried changing the IACV for a known good one?

jarvis199

yes i have, same result

known good ecu? double checked all wiring?

ive made some wiring mistakes...... especially with the o2 sensor conversion

jarvis199

didnt hav eto convert o2... its a 1992 all in dash harnesses are same (just had to run 2 vtec wires into the dash harness, swapped ecu out for the stock cx p05 and same problem occured...

hmmm quite a pickle.... the iacv is not spotless?? it has to be the wiring... sorry i dont really know what other info to offer

jarvis199

fixed, pulled the manifold, heli-coiled 2 bolts on the throttle body and 1 on the iacv, cleaned everythging and reinstalled, could have just not had a good wiring connection at first, i dont really know what it was but it seems to be fine now, thanks for all your guys help...
