ok, got a jdm h22a in my 98 hb. The motor drops the rpm's to 300 or so and then picks back up to 750 or so over and over. Also bougs pretty bad at low idle when gassed and back fires more then usual. I turned the distributer retarded all the way and it smooths out the idle. Any ideas whats going on?

did u **** with the timing at all? And also is your egr hooked up?

Still having problems? Someone help this man out.

I bet you're getting code 12 (EGR) too eh?

idle fucktuation is commmon with H22 civic/integra swaps.

Read this thread on how to remedy the idling issues:

He said he wasn't throw'n a code in another thread. He has also been trying a couple different ECU's.

..my baad..

Well, he didn't quite say he was or wasn't throwing a code, nor was it mentioned he was trying different ecu's till now...

all good tho...

He has had several different threads about ideling/ECU issues......that the only reason why I know......yep, it all good.

PS-I run the p28...no EGR for me nor have I had any idleing issues.

Yeah, not throwing any codes and im running a chipped p28 with no egr hooked up. Im almost positive its the timing. Got a tool to pop the crank pully off so ill take a look tonight.

ok, I lined all the marks up on the cam gears and camshaft and it almost looked like the intake gear was off just a tad so I turned the adjustable cam gear to where it looked right. Started it and it still idles up and down but sounds like its gonna stall each time it drops to low idle. Could 92-96 timing belts be different then 97-on? I know the part numbers different and I have a 99 belt on a 92 jdm.

yeah the timing belts are differnt.

i had the same problem on my 92 cx but i got the belt replaced and did some adjustment on the cam gears, and it runs like a champ now..

Recheck your vacumn hoses for leaks or just improper install. Also check plug wires to make sure you got them on in proper order. ..

Different timing belts for H22's....wtf? I have never heard of that nor does it make sense.

I had the same problem with the firing order before.....

What's different about them?

BaNAnABoAt689

the length of the belt. not to a extreme degree but different.

when i got my jdm h22a on my 92 cx, i was told that from the shop that did my swap.

skunked

well if the length is different that means the deck height, pulleys or something along the lines of that is different. I'm going to have to search this one......it's bugging me.

ok, I reinstalled the timing belt and did a compression test. All cylinders are above 200 easily. So I replaced the ditsributer cap and the idle smoothed out and it runs great now. Thanx for all the help. Anyone know what the gaps for the plugs should be?
