About 4 weeks ago I hit a deer, I took it to a highly recommended body shop to get some work done and they replaced my bumper and it looks great. However, now that I just got my car back my MPG seems to be like super sensitive. Before I was getting 27.1 and when I would get on it for awile(riding high rpms) it would drop to like 27.0 or 26.9 after an hour or so. Now my MPG is at 25.7 and if I hit the throttle to accelerate up a hill it’ll drop to like 24.9 in a matter of seconds. Is this normal? I didn’t know if maybe something couldve been unhooked during Maintenance or reset somehow. Thanks.
