I had installed 290cc Prelude injectors on my motor prior to sending it to the shop....and had requested them to replace the injectors with my stock 240cc GSR injectors. I just got the car back....and haven't started it up yet and I'm not sure which injectors are on there. I'm pretty sure the guy just left my Prelude injectors in there....cause I had to cut off a notch inside the plug to fit the Prelude injectors inside. Anyone?
