my cousin has a 91 b18a in his 89 crx. it has a b16 transmission and a zdyne ecu off of his old b16. it ran good the first day but after that it started having a weird jumping problem at low rpms. what would be the problem?

my car does it too. check vacuum lines and the TSP. the ECU is for a VTEC engine, you may want to get an LS ecu (PR4)...
