Check engine light is on and the vtec does not feel like its engaging. Looks like codes 21 and 23 how do i go about fixing this problem myself or leave it to the honda specialists.The engine is a b16 swaped into a 91 honda civic.

 

vtec isnt working cause your prob running in "limp mode"
are you running obd1 or non if obd1
code 21 is your vtec solenoid also why vtec isnt working
code 23 is knock sensor
hope i helped let me know if you need anymore help

 

yes but I mean how do i go about fixing this .......or am i screwed

 

more info is needed about your setup r u running a knock sensor still or was the ecu chiped and removed check your oil make sure the sol is wired correctly make sure knock is wired if using it many factors
