Re: new to S-15
Good choice! I wish the new Jimmys/Blazers [img]/wwwthreads_images/icons/frown.gif[/img] would have kept this bodystyle, it's classic [img]/wwwthreads_images/icons/cool.gif[/img] (In my opinion, they should have kept the old Camaro design also).
Anyway, one of the most important things to do is to check the vacuum lines. [img]/wwwthreads_images/icons/tongue.gif[/img] This could be the problem when you have reached the point of, after trying everything else, "What the hell could it be!" [img]/wwwthreads_images/icons/laugh.gif[/img] In fact, replacing all of the vacuum lines (and the one to the transfer case) is the best, overlooked, preventive maintence.
Besides the K&N filter, I have installed a Holley TBI. [img]/wwwthreads_images/icons/cool.gif[/img] I definitely noticed an increase in acceleration and 5th gear power. You could get a performance chip also, but don't do both, there are conflicts. [img]/wwwthreads_images/icons/crazy.gif[/img]
If you don't want to spend too much money on tires, and with that, body lifts, etc., think about buying 235/75/15 size light truck (LT) tires (they will give you a stiffer sidewall for off-roading). I bought some from Pep Boys...Futura (made by Cooper) Scramblers [img]/wwwthreads_images/icons/cool.gif[/img]...I have had them for nearly a year and they don't look like they have lost any tread yet. [img]/wwwthreads_images/icons/smile.gif[/img] They are a good all-around tire.
