Is an Idle RPM of 500 the proper Idling number for a 2001 Mustang GT V8 while in drive?
Recently, I had my Mustangs Intake Manifold replaced, due to multiple cracks on my old one. I am just curious if the 500 Idle number is where my Mustang should be at while stopped at a red light or stop sign. Mech inquiries would be great!
While in Park my idle is just under 750, which I believe is good and overall my car runs much better than it did when I had the cracked one, however, it just seems like the 500 number while in drive could be a little low, but I have heard it varies from car to car and it should be on the lower end with a V8.
-I should also add that my car has been running off old gas, at least week old from before I brought it into the shop to have my Mech put the new manifold on. could that effect this? if it is a tad lower than what it should be?
