I have a 1994 civic ex with a jdm b20b block and jdm b16b obd1 head and an integra gsr trans on a chipped and tuned p28 ecu. The car runs amazing most of the time. But once kt gets warm it will randomly bog down, than when i release the pedal and repress it will come back alive and drop back down. Than itll stop doing it and drive normally after a second or if i restart it. Ive changed plugs and wires. Fuel pump and filter. Cleaned my injectors and inspected the wires. Anyone know where to start checking next? It also comes along with a random misfire but no cel.
