I have a 97 prelude with an h22a enigine (OBD1). however when the engine was put in the OBD2 computer was left in. now about 2 months after the swap my check engine light is on. the codes are po700 and po740. im not sure if it has anything to due with the computer not being changed or if there is something else that is wrong. if anyone has any advice, please let me know. thanks

 

would like to know if you ever found out anything since im also doing a h22a into a 97 lude?

 

also what did you have to do differently to get the motor running as im having problems w/ my mechanic saying theres no place for the crank sensor on the h22a?
