YEa I also have a 2001 DTs it only has 102k miles, I stall out time to time while idle never when giving gas, and sometimes its hard to start, I even recently noticed the rpms going up to 3 when i'n not giving gas, I changed the fuel pump, had a tune up, but it still gives the same problems from time to time, and also my computer keeps telling me to check coolant, and tire pressure??? my brother has a 02 dhs and the same problems any ideas?
Had the same problem with my 01 deville with the high idleing or low idleing, I replaced the idle control sensor , problem fixed... just 2 days ago caddy jus tricked the 410 code secondary air injection system but this system has many parts any advice on where I shoud start looking to fix the problem?
