I just got finished swappin my old obd0 dohc zc with spun bearings for a new obd1 sohc zc. I got it running and passed emissions, but it is still not wuite running right yet. After the car warms up at idle the motor will sputter a little every now and then and has even died once. Also under a load at low rpms it will sputter and pop. It usually stops around 3k then i can go full throttle with no problems. my timing is right on( checked it many times) What could cause this only when warm at low rpms?

 

bump for some suggestions

 

vacuum lines maybe??

 

nah, i checked visualy and with a guage
