so im throwing a code thats EGR Valve - Insufficient Flow. i taking the valve off and cleanin the carbon out of it the best i could and replaced the gasket. hoping that would fix it...it didnt. the code comes on and off every couple days and wont stay on but for maybe half a day. its weird. and also when the check engine light comes on my TCS light will come on as well. this usually turns off the next time i start my car though. any suggestions? other than maybe i have to replace the EGR Valve itself. i have a 2001 CL-P with 109,900 miles. maybe this is just regular tune-up for this part? thanks for any feedback...
