Hey guys. I just finished my H22 swap and I got it running today. It idles pretty good but once i start driving when i let it idle it wants to stall. Then when im driving and give it gas it bogs super bad when the rpm wont even go up, but when the clutch is in or when its in neutral it revs up just fine. Theres a bad air leak somewhere. seems like its coming from the throttle body. I never changed the gasket when i took off the throttle body. Could that cause this? Any help would be great. thanks

 

sound like it could be a vacuum leak, also when i finish my swap from h23 to jdm h22 0-4000rpm no power, car would struggle to move but once past it hit fine, again when clutch pedal was in or in nuetral it reved fine, it turned out to be my ecu was defective, switched it out and it ran fine. well hope that helps

 

I would double check the timing and see if you have a vacuum leak. If you took the throttle body off and didn't replace the gasket it is possible this is the problem.
