I am looking for some help with my 99 2WD, 4 Dr Blazer. Number 1 I have the sagging driver door issue, which I think I have figured that one out by reading all of the other posts!!

The second problem is horrible gas mileage like 10-12 city. I replaced the plugs,air filter and fuel filter, didn't help. From reading other posts I guess I am going to replace the cap and rotor. After reading several post, I would like to know if the 99 blazer suffers from the CPI leaking problem or is that conifned to the 95, 96 models? When I fill up with gas I can smell some in the cab but it goes away after a minute or two, and right after I fill up is the only time I smell it, any clue?? Any help would greatly be appreciated.

The blazer we own also has a sagging door problem. 97 model to be exact. common problem due to wear.
