While doing a search, I came across these two posts. While they say the same thing, the first states that it is for the s/c engine. The link in the second post states the recall is for the n/a engine. Is there two recalls, or is the recall for either engine? I have the issue on a 99 regal gs I just picked up, and if gm is willing to take care of it for me, then by all means it can be done on them since it is to cold out for me to do it. I am just looking to have my ducks in a row before calling them.
