i have a 1998 db7 integra with a B18b swap . My problem is that it will randomly lose power in low rpm then slowly gain the power back if I slam the pedal to the floor . Already changed plugs and wires and injectors/fuelrail . seems to only do it when the car is at temp . Any tips ??

 

Hmmmm,sounds a bit like the valves aren't seating/sealing properly due to carbon build up??

Might be worth squirting some water through the throttle body to clean the upper head.


Check tps voltages.There's a diy on here by a nice guy.
