i would have waited for Tire Warehouse to order them, but i needed it up and running today.

 

If you go to a dealer, make sure you have the VIN with you (or know where it was built) because they put different ones on at different factories.

For some electrical parts yes, but not O2s. There is only the 4 wire flat kind and the 4 wire square kind. And the 4 wire flat kind arent used on our trucks. Only the 4 wire square ones. The F-bodys have simular but different plugs. There plugs are swapped from what they are on the trucks.

 

Sweet, thanks for the link. I may have to get some of those. For the 126 leaded stuff.

 

THAT MIGHT NOT BE RIGHT FROM YEAR TO YEAR BECAUSE I HAVE A 2001 AND MY FRONT O2s ARE THE FLAT PLUG AND I HAVE SEEN SOME 99 WITH THE SQUARE PLUG SO I THINK IT MAY BE ALSO DIFFERENT FROM YEAR TO YEAR PLUS WERE IT WAS PUT TOGETHER .

 

Another common thing, check the fuel pressure regulator. The diaphram blows out & puts fuel in the vacuum line, hard starts rough run rich etc.
