i tried to observed it more i noticed that the fuel pump is priming and it clicks so it can't be that,it starts doing the problem after 20 min. of driving but not all the time like i said it's random, and it does it when i hit a bump or the road is a little rough, it feels like it's not geeting enough fuel or spark.already did a fuel injection flush and changed the fuel filter amonth ago and worked perfect for few days before it start acting up again,got my fuel injectors checked out and the result are the pressure are all even, i'm already tired of this guessing game, i don't know why mechanics can't pin point the problem it would make life easier, just paying them money for nothing even i already went to three acura dealers and they can't figure it out, by the way i forgot to tell you guys and ijust remembered now, the problem started after i put that lucas fuel additive, coz i think that additive has lead on it and it's an upper cylinder lubricant that means it has oil on it ( imagine putting an oil in your gas tank)i don't know if it has something to do with it or it's just a coincidence, but it's been like three months now and it's still doing that crap, i need your input guys coz i can't rely on mechanics here where i'm at, thanks in advance.
