Mazaev Posted October 21, 2012 Share Posted October 21, 2012 So recently I noticed my 99 with 27k miles is using up a lot more gas. It's been like this for the last 4 tanks and I'm hoping for for a suggestion on what it could be. Washing the Pipercross filter as I type this and planning for on pouring in some Seafoam, but besides that, I'm not sure where to go next. Valves and throttle body sync were done 10k miles ago and there is no brake rub. Link to comment Share on other sites More sharing options...
