Besides the 91 RS... we have a 01 chevy venture mini van. We just found out that we need to replace the manifold gasket. The problem is that the price of the repair depends on the emissions, California ($650) or "not California" ($1000)..... I looked under the the hood for the emissions sticker and all it says is "This vehicle conforms to U.S. E.P.A. NLEV regulations applicaple to 2001 model-year new LEV light-duty trucks. OBD ll certified".

 

You'll need to contact your local Chevy dealer and have them run the VIN number. I'm sorry but this board is limited to help with thirdgens only.
