at which rpm would a v6(3.1) run its best and get the best gas milage? is it in the 2500 range or something else?

 

just about 1000, yep, good gas millage, good smooth idle, no problems....1000 rpm's everywhere , round town, highway, race track (go easy on er) and she'll get 70-80 mpg. All truth and honesty, i think mine was doing 2700 or so on the highway, 70-75 mph, ran fine, good, and strong....until these problems invented themselves.

 

Doesn't an engine use MORE gas at idle? Isn't that why running the car while waiting for someone for a long time is not recommended if you want to save gas?

 

thats what i thought, with the idle thing...i wasnt sure what our cars have for a good rpm to cruise around in.

 

i was under the impression that an engine is more effecient at higher RPM's however, i was also thinking that although more effecient, the higher RPM's will cause more fuel consumption, as the engine is moving faster (easier to stay in motion) yet for mainting a propper A/F ratio at the same given RPM more fuel consumption would occur.

 

You just gotta make sure n only use as much pedal as you need. Real light n easy. Its to easy to over use it on a FI car. A tighter return spring can help. I run super tight ones on my carbed V8 car.

It makes you keep it easy. The weight of my foot is plenty to get up to 40-50 in a reasonable amount of time.

 

having to wind out the motor to keep pace with traffic doesnt help.
