I am wondering if you hook-up the scanner and I hope you getting failure code. Also, while scanning for code, try to look the live feeds (activities) such as the TPS. Try to clean the TPS. How about the vacuum hoses, check for leaks. The last option is the DME/ECU. I have issue before with my 323, at idle works perfect but when revving the engine, I got a rough, sounds like misfiring. At first, I thought the TPS but it responded perfectly with the scanner when accelerating. So, I decided to replace the DME/ECU, and EWS with key chip. Check this site and read the symptoms of bad DME/ECU. |
