New to the forums. Thanks for reading my post but i have a 98 Prelude with a JDM H22a. jst found out that my brother hasnt swap anything from the H22a4 motor to the H22a like the oil pump n such. With the US ECU its throwing a CEL with 6 Codes. 4 of the codes are misfire in all 4 Cylinders. What can i do to fix the problem?
