Engine Performance problem
1998 Chevy Astro 6 cyl All Wheel Drive Automatic 109000 miles
A service center recently replaced the intake manifold. Since then, mileage has dropped form 20 mpg to 11.5 mpg.
The service center has not been able to correct the problem, even though I have taken it back to them on 3 occasions since the replacement of the intake manifold.
I am not seeing any indicators to tell me that there is a problem with any of the systems.
What should I consider doing next? This has been a very dependable ride up until now.
have the same problem?
