hi, i am new to site. bought a 91crx with a b18 swap already done. been drivin it around for a month or 2. the other day i hit a dip in my dirt road and the car wont rev past 3500rpm. i replaced the throttle body, the tps sensor, and found some wiring that was loose. fixed all that. the car idles better but still wont go past 3500rpms. i have a pr4 computer. it acts like it is limp mode i have already ordered a new one. do you think it will help or is it somethin else. thanks for any input.
