The computer codes will read misfiring on random cylinders, and also will list certain cylinders, but the readout will change if I reset it at times. It read this before and after I replaced all of the spark plugs and solenoids. Seemed to help, and then even solve it. Then would do it once in awhile. Now daily just like 6 months later. Often it is accompanied by the VSA light coming on with the yellow exclamation triangle. I know someone out there knows how to fix this. I have taken it to several mechanics, and it either would just not act up for them, or they would be stumped. Even Acura mechanics acted baffled. Please help me

Oh yeah, I did clean and check my EGR. I heard could be bad fuel injectors, catalytic converter, compression, vac leak... This car is now 17 yrs old with 200k miles, but ran great as a daily driver til now. I feel as though I could waste a whole lot of time and money chasing this problem without alot of luck or results as there seems to be alot to rule out. Possibly too costly for what my car is now worth, 2K at best

Unplug one coil at a time with the car running. The car should run noticeably worse each time you unplug a coil, if it doesn't then that coil is the culprit.

I think some people said if the car doesn't have the issue all the time or the coils/plugs don't fix it, it may be an injector.

Also, when was the last time you adjusted your valves. An Acura Master Tech I know told me our cars like the valves on the loose side of the adjustment and are pretty sensitive affecting the MAP voltage readings.

I had a very similar issue a few months ago, ended up being a bad injector.
