it started last year when i boosted my single cam and put some dsm injectors, have been obd1 and running hondata s300 for a while. but sometimes ill start the car and it will run on 3 cylinders, i just drive it for a little while and it goes back to normal. ive tried 3 different resistor boxes, but havent checked the resistance in the wires. its just weird that its so random. oh, and i just swapped to b16 the other day and is doing it more often. any thoughts? the injectors were remans by the way
