I know this issue has been beaten to death but can we go over it one more time? I have a 99 auto sportage. The car seems to start fine after sitting over nite but when I give it a little gas the first time it stumbles. After that its fine. Thats been going on for some time now. Now, not only does it do that its also stumbling and hesitating a little bit during normal driving. Its getting worse. No codes yet. Plugs were changed about 15k ago. Everything else is the same. The valve cover gasget will be changed in a couple of days. Where should I start? It has 66k miles on it. The list seems pretty long, from gas filters to screens on the cat. Although on the way home tonite it ran perfectly. thanx for the help.
