  6. Fuel system

    This forum is a GAS. How's your milage? Change your fuel filter lately? Oh- that noise you hear when your truck is running is normal: it's just the submersible fuel pump. When you don't hear it is when you need to worry...

  7. Wheels

    The round metal things that your tires are attached to. Stock ZR2 wheels are called "PA3's" or "N90's" and the size is 15 x 7 with 6in. of back space on a 5x4.75 bolt pattern. Not sure what "back spacing" is?? Well you better find out before you get aftermarket wheels!!

    Those 4 round, rubber thingies that make your Z roll. There should also be a 5th one somewhere in your ZR2 with adequate air pressure. Stock size is 31/10.5/15.

  15. Ask Mr. Mike: GM Engineer

    You may already know Mike. He built the baddest ZR2 that has ever roamed this earth. He drove his ZR2 in Petersen's 4-wheel/Off-Road "Ultimate Adventure" in 2003 and impressed a lot of people with an IFS S10. A "wealth of knowledge", but also an extremely busy man these days. Ask him any specific ZR2 question you may have that you don't feel could be answered elsewhere in the forum. Please be precise. Please be patient. His professional and experienced answers are well worth it. Be sure to visit his website before you leave!
