Hey all, just got done cleanin my EGR valve yesterday, what a mess, lots of carbon in there, cleaned it out, but didnt solve my idle problem, checked the computer code, and got a code 22, throttle position sensor, but cleanin that EGR valve out definatly helped my acceleration a lot. so even if its not a problem in your car, but you have a lot of miles i recommend cleaning it. so gonna replace my TPS next week, and ill let ya all know how that goes.
