I have a first gen b16 in my 90 crx si. while cruising/driving my car chokes out and studders if i punch it or have at higher rpms it does not have a problem. me or my mechanic can not figure it out. compresion and timing could not be more perfect. Any ideas???

 

This happened to my car, only did it once in awhile here and there. First noticed it at low RPMs in 3rd gear then eventually got worse. Ended up being the dizzy, went out very slowly until it totally siezed up.
