Ok I just got my h22 into my eg. Had no engine codes. The car has a little rough idel so i decided to take it for a test run. First the car stumbles and has a very long pickup till vtec. Once vtec hits it pulls hard. And when I let off the throttle after the stalls. I just recently got a code 41. I cleaned the o2 sensor checked all the wiring and the o2 everything looks good. Please help Thanks.

Check and see if it's running rich, might be why it's not running well till Vtec. Another question, do u have a Vafc?

Kinda weird just went out to drive it again and was supprissed bye the pull. Ran great.. still staled but ran good. No im going to byr the vafc neo this weekend. When i lifted the hood after my run it smelt real rich.

hmm, now that u sa y u got ur O2 sensor working, it shouldn't run as rich, try making sure ur map sensor is running good, mine wasn't for a couple days and it ran real rich, hmm u can chech ur spark plugs to see if u're running rich too, and the back of ur exhaust tail pipe to see if there's alot of black crap, also, did u replace ur spark plugs when u did the swap? i didn't replace mine for like a week and they were crappy and weren't igniting every time so it would run a little rich and bad, but otherwise, just try breaking it in a little bit more and see how stuff goes, let me know how it turns out.

yeah I installed NGK as soon as i got it. Im going to try another oxygen sensor.. Im getting a code 41 which has to do with the heater portion of the o2 sensor correct? Other than that all my problems seem to be from running rich. I did just notice the sheathing on the spark plug wire waw cut. gonna try replacing them too. Well thanks for your help. I hate little problems like this cause it could be a million things

Yeah i've had a million little problems since I got my h22 swap working 2 weeks ago. Yeah code 41 is the primary oxygen sensor heater I believe. I had that code cause my oxygen sensor connector came off randomly, haven't had a problem with it since though. Good luck to ya, hopefully once u get these little things fixed it won't run rich anymore.
