One simple button with a choice . Economy or Sport mode . I believe it would have saved many many complaints .

You're not the only one. Because it's easier to turn of AFM than adding two cylinders. so long j-ten-ner

Well I can see the difference right away. I don't have much flat ground and around here, Chicago area big wind is life. That said. Being on and staying on is quite something else. Yea, it turns on but

  As much as I love the S10 Blazer (owned more than one, back in the day!) they were never at the forefront of safety. "They don't build 'em like they used to!" - thank goodness. Pour one out for what looked like a nice example of a clean old Blazer.

  Have a Silverado Custom 2500. Try out the seats ahead of time but can always add a pad or two if necessary. Love my truck. Only feature I thought I’d miss is Auto 4WD, but after driving it a few years, realize that it’s not necessary.

  The amplifier was replaced in February and still happens, still waiting to hear from the dealer that the replacement radio came in.

  By PBNB · Posted 3 hours ago
  
  I have been looking at ways to reduce the crud in the intake manifold and one way seems to be preventing the oil from entering the intake and mixing with the soot from the EGR. VSE seems to have a CCV kit that looks like it takes care of that. Add to that a FASS EGR Filter kit and the intake should be pretty clean. Any thoughts on either of these add ons?
