Dave, If there is a lean condition via the WUR it will do this. I have a cis tester I can loan before you buy one and try it. I have them for $139.95 with a 3 year warranty.

DeLorean needs help Hello, I have been living in Steamboat Springs, CO for the past 6 months and just returned home to Michigan for the summer. I was pleased to have my car start right up on the first try. Unfortunately the car is not drivable until it is fully warmed up. The car sputters and chokes through the intake when it is given throttle when cold. The lambda light just turned on today as I hit 30,000 miles but that should not cause my problem should it? This car ran perfectly before I left. Any thoughts on what I should look at? Take it easy Dave Phelps 6286 [Non-text portions of this message have been removed] To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
