Hi,
I am new to Grandprix forums, I own a 2000 Grand Prix GT and had a question.
When I get to about 60, the rpm's are at 2000. When I get to about 73, they are at 24-2600. This seems a little high to me. My mom has an 05 impala and same engine and runs about 2000 at 73. My cousin has a 02 monte carlo and it runs 2050 at 73( I asked him to try for me) I don't get horrible gas milage but it seems down a little. about 24 mpg vs 27 for my mom and 28 for my cousin.
Any advice would be really nice. I also don't know a whole lot about specific car parts so please bear with me
