Why is it that when I shift into a higher gear it feels like my car is getting really slugesh, its a 95 vtec and when the vtec should be engaging its feels like its not putting out enough power..What can it be? Ive just gotten a major tune up(fuel injector cleaned,fuel lines were cleaned,new spark plugs, disturbuter,disturbuter wires,oil changed and oil filter replaced) what can it be, could it have something to do with my Vtec solenoid ? Any help would greatly be appreciated!!
