Alright guys, I have a serious problem here. I just installed a B16 from HMotorsonline, the complete change over including all hasport hardware, even sub harness. There is a bogging and misfire through the whole rpm range and only one sweet spot on the throttle where there is no problem. There are no codes what so ever. Is there any one on here who can help please. The car is a 88 CRX Si. Thanks to all who reply.

**UPDATE**
I got home from work and started the car and it rev'd perfect. took it out for a test drive and it did awesome. warmed up a little and then vtec engaged. but as soon as the car got to normal operation temp, it started doing it again. very boggy, and vtec was intermittent. What could cause this when the car warmed up? Pls help, wife is getting mad that I have to take her car to work!!!!

Your o2 sensor wires are most likely mixed up, try switching them at the ecu and see if that fixes it.

 

will it make that much of a difference? I am just asking, not saying you are wrong.

 

check timing, clean out eacv, check tps voltage, make sure your throttle cable is tight but not so tight it opens during idle. im currently trying to figure this out on my mpfi swapped d15b2 but no luck.. i have also read alot of the b16s doing that when the o2s where switched. im kinda new to the honda stuff but im a fast learner and i could also be wrong but it sounds like timing is an issue too.

Made a big difference for me. Is it fine at full throttle?

 

no its not. it still bogs like crazy. I will switch the 2 o2 sensors and see where that gets me. Thanks
