Replacing CKP sensors
Good evening, I have a 2002 Eldorado which stalls as soon as I start it if I don't hold my foot on the gas peddle. Back in May this happened but the alternator went bad at the same time so once I got the car back on the road I thought that was the problem. 2 weeks ago it left me in a parking lot stalling as soon as I took my foot of the gas. I checked for codes but there wasn't anything.
to make a long story short, I decided to replace the sensors since I read on the forum about the 2000- 2004 Northstars with defective sensors ( one black and one tan). So I ordered the new sensors ACdelco 12575481 (grey) and AcDelco 12575482 ( black) and decided to replace them this evening. When I got to the old sensors they were the same ones. Does it make sense that the sensors are bad or is it more likely there is another issue that is causing the stalling.
Thanks for your help,

Your symptoms aren't caused by failing CKPs. When was the TB last cleaned?

Could be different things, like egr not working properly, vacuum leak, a ground problem, etc. I changed the ckp sensors on my 96 and it cured things, but there was a random misfire code and the tach didn't work either. Also had to re wire everything... I'd say since you already have them go ahead. There are a couple of threads here pointing out which goes where... Good luck!

Re: Replacing CKP sensors
Thanks guys . I cleaned the throttle body at ~ 95K when i did the Plenum gasket ( I am currently at 104K).
Thanks for the suggestions I guess I will just replace the sensors since I have them and investigate a few of these other things.
thanks for that link I didn't clean the IAC when I did the throttle body so Ill give that a try tomorrow.
