My first question. engine is missing
I have had my 93 Sentra SE-R for a couple of months. it ran perfectly. but recently it started missing as if it was not getting spark to one of the plugs. so i changed all the plugs the wires, cap and rotor, coil. problem went a way but now it started again, but it comes and goes. checked the wires and stuff again that's solid. could it be fuel injectors starting to lock up, could it be the distributor?. I check the pump and it works perfectly. any help would be greatly appreciated?
