Acura Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Can you tell me if the check engine light is coming on at all?
Sorry for the delay in getting back with you. I was not available to get online earlier. If the check engine light is not coming on and you know that it is an issue with that particular cylinder then it may be a slightly clogged injector or some carbon build up on the valves. It can also be a vacuum leak near that cylinder but I do not see that often on this engine. I would run some seafoam through the intake and see if it clears out any carbon build up. If that does not do it use a good quality injector cleaner or have the injectors professionally cleaned.
An injector issue would not cause this unless there was a misfire code. If you do not have a misfire code then the fact that it is losing spark would be either related to a failing ECM or the circuit.
