ok so i got the job at werner trucking which is a hours drive from my house. right now my car is running rich and im wondering is it better to run rich or lean?

 

Rich, if you run too lean, you'll be buying a new engine. Although I'd be nervous about depending on a car that is running rich, what's causing the problem?

 

both aint good but rich is better lean youll lock up the engine rich youll just get crappy gas milage and blow black smoke out the exhaust pipe. since your gonna be driving it that far might think about geting a overdrive tranny for it and maybe re gearing it too.
