Re: Codes 171 & 174 TSB # 03-16-1 update

humbug1, to answer your questions:
1) No you do not need to take your van to the dealer immediately after the CEL. Some people have driven for thousands of miles with the CEL on. The first time the light came on in my 2001 van was in Jan 2005, I had it reset by Adv.Auto. It did not come back on for another year. Yes, Dec/Jan 2006. Must be some thing to do with the NC cold. Well this time it came on in Nov 2007. I reset it and it came back again after one week. I knew it's time to have it done. I did it my self. The improvements I saw was that the engine was running very smoothly. The pinging noise on acceleration was gone also......I do not recommend you drive for long period of time or for long miles. Just have it done as soon as you can.
2) The post above mentions a repair quote of $895. Others have mentioned $700 to $1200. Depends on how greedy your local dealer is. I am sure they can do the job in 1.5 hrs.
