hey all, I just swapped a gsr motor into my del sol, The motor is a 12:1 compression motor with a light tune and its tuned to run on 93 octane, I drove the donor car to my shop to do so with zero issues, I swapped everything into my car and had 87 octane in the tank (about 1/4 tank) I threw in some fuel additive and drove it nicely to waste the existing fuel before refilling with 93 octane. I have now replaced the 87 octane with 93 octane and I am stilling getting this code, if I turn the car off then turn it back on it goes away, and if I drive the ca without hitting vtec I get no code, the instant vtec engages it throws the code, as I said the donor car dd not throw this code, ad I checked that cel too, it wasn't blown or anything. any ideas?
