The error also comes and goes while driving but doesn't affect the performance of the car, the engine still runs smooth. I took it to diagnose the issue, the computer shows Engine Throttle, Sluggish/stuck. the mechanic said it could be a throttle body issue, he check the throttle body and its clean. He cleared the error and said you drive first and see most likely need to replace the throttle body. Any of you encountered this issue before and any tips to rectify this. appreciate your input guys. Thanks in advance</p></blockquote><p></p>
