Loc: St. Louis, MO
Motor: B18C5 Integra Type R
Mods: "Rocket" full valve train with Skunk2 Pro 1 cams, STOCK block
Engine management: Apex'i Power Fc with the stock B16B fuel map and ignition map

Important info: I have the Type R motor from an '00 Type R. The motor came without the exhaust header and intake manifold. I am currently using my OLD stock OBD1 B16A intake manifold. Along with this I am using an OBD0 / 4th gen Civic fuel line/ fuel rail.

Problem: Motor idles fine at first, but after 7 mins, the idle goes from roughly 300 rpms to 1,000 rpms. Normal idle is roughly 650-800 rpms, from what I have noticed. Fuel pressure consistently jumps from 50psi to 60 psi. This jump in fuel pressure could also be causing the idle problem. There is also an awkward "knock" / noise coming from the head right off of the dizzy.

I haven't driven the car much / hardly at all due to the larger cams and I'm not wanting to hurt anything motor wise.


Any info is appreciated and thank you in advance.

i'm gonna go with a- you're untuned with an incorrect basemap.
and b- they're high lift cams, they're not supposed to idle at stock rpm's.

Well I figured that much too, but I'd rather be safe than sorry and to risk ruining anything... I plan to have the car towed to the local tuner and have him finish the car next week.

But as for the 300-1000 rpm rev intervals, that doesn't seem normal either, even for high lift cams, and the IACV is fine as well.
