I have owned this Chevrolet Blazer for 4 years. 1995 was first year for the vortex engine. I had an expensive repair of the cfi unit in July, 99 and now again 16 months later, cfi unit needs to be replaced along with the catalytic converter. There is also an ongoing problem with the egr valve. Chevrolet sent out a notice about problem, and I had my car serviced last March. But, same part was just replaced with a new one. If the valve is sticking the design of the valve should be correced. Carbon builds up again in the valve and this will be an ongoing problem. I sent a complaint to Chevrolet, but their letter back to me was a note to call the customer service. When I finally got through they said thanks for calling but nothing else. Overall, very disappointed with how this company is handling a problem that my mechanic says it is widespread. He has trouble getting the part since so many are needed!
