I just put a b18c1 in my honda it has 11:5:1 compression ported and polished head skunk2 cams and cam gears stage 2 with aem fuel rail and regulator and knife edged crank. since i got it hooked up it has not idled normal the idle is jumpy is that normal for my setup or is there a problem? i have a chipped p72 ecu also. help please!!

 

Vacuum leak possibly, does it surge up and down?

 

same thing happened to my H22......just take out the fuse for the ecu to reset it........i did a couple months ago and its idled fine and i havent lost any power or had any problems since.

 

there are no vacuum leaks that i know of. i shop told me it idles like that because of the cp and i have bigger cams. can that be why?

 

the cams and cr are not going to make the car idle rough enough to notice. I would take some brake clean and spray it everywhere on the intake manifold and see if the idle goes up or down.

 

if theyre really aggressive cams it could be those

 

nah even big cams don't make your idle jumpy, i have same compression as you and stage 3 jun's and the idle is stock (800rpm).

 

just try reseting your ecu it only takes a min and it worked great for me!

 

how you do that i have disconnected the battery and reconnected it and it made on difference.

 

disconnecting the battery wont do it.......but in my H22 all i needed to do was open up the fuse box in the engine and it was a red fuse with 10 on it and labeled 10A clock radio on the fuse box. take that one out if you dont have a fuse labeled ecu, just leave it out for a few minutes and stick it back in, it did wonders for me

 

I'll try that too because I tried everything for my H22 surging idle and i'm getting pissed off.

 

My idle jumps now after boring my TB, and never did it before!

 

we gotta figure this out it is annoying. my car pulls to 9500 rpms no prob
what stage cams you think i got in there?

 

???????????

 

i reset the ecu didnt work any other ideas? some one said change the thermastat could that be it?

 

when the car isnt warmed up all the way it usually idles good if that gives you any ideas

 

I had the same problem with my stock B16 and figured out the TPS needed adjusted. Do search for procedure. Good luck!

 

what is the TPS sensor? whats it do wheres it at?

TPS = Throttle Position Sensor

Its on the back of the TB facing the firewall!
