When I start the car it always rev's to about 2K rpm and drops off to 750 at idle.

I'm not sure if this is something that's normal or a result of the headers and catback. Perhaps it's just that I can hear it more. My gas mileage has dropped off quite a bit to about 18mpg on mixed driving.

I don't think I want to jump into the whole SAFC II discussion again, but if it makes a difference, i'm interested.


Thanks for the help.

normal on both cars i drive, the maxima and a CR-V. the crv revs to 2k and starts decling as she warms up, when she gets under 1k, i go. the maxima revs to about 1500, and within 3-4 minutes drops to it's expected. i wouldn't be worried. that's perfeclty normal.

 

Yea mines too TREX normal. once it gets warmer it drops to normal rpms.

 

Your headers and catback are making you run rich.....

 

And, let me guess, the only way to fix that is to get an emanage ?

Thanks,

Not if its normal TREX. are the rpm dropping when it gets warmer? if so no.

 

sound like my start up and idle are pretty normal but the drop in mileage may be a result of adding the headers and catback. I'm gonna guess from having read many of the posts on the SAFC II that I could improve perfomance and fuel economy.

Oh no ****. MO MONEY MO PROBLEMS.

 

it's normal, my car revs to 2k when i turn it on, and it drops to 800~1000( auto) in 3 secs.

 

No problems...I just want the best of both worlds...great gas mileage and the most performance.
