I just installed my JB+. I took it for a spin and under 4000 RPM no problem....i decided to push the car on DS mode right after I passed the 5000 RPM the check engine light came on, I slowed down and stopped thats when the car started to shake so i decided to shut the car off.....I turned the car back on and the check engine light stayed on but no shaking....Any suggestions on what to do before i remove the JB+???
