ok so i have a 1993 honda prelude 5 speed with 221k miles it runs good and all but for some reason when it engages into vtec at 5000 rpm it doesn't accelerate normally its like its bogged down and i recently put in brand new ngk spark plugs, im thinking it could be due to old spark plug wires the connections look in alright condition, or maybe the injectors, i was thinking about running fuel system cleaner through it, there isn't any check engine light on , the car runs good up until that point, im using 93 octane fuel but on my last fuel up i accidentally put 2 gallons 89 and then put in 5 gallons of 93. then once all of that was out when i refueled i put in shell 93 v power it ran better but still has the same problem..what should i do
