Hey guys whats up.... i dont know what happen to my fit.... in normal idle ( when its still) the RPM are around 900.. but when a put in neutral in a downhill i noticed that it get to 1300 - 1400 rmp... but when i stop again @ 0 mph it get to 900 rpm again... its normal? or maybe i broke something? tell me what you think people...

thanks

juanpo...


P.D. Excuse my English...

 

anyone??? please???

 

is your ac on?

I am assuming you are automatic? it probably has something to do with the water pump and autos not being designed to be driven in neutral. That or you have a vacuum leak.

 

mine is manual... and the ac is off.... i will chek all the vacuum tomorrow and see it.... someone told me that i need to reprogram my ecu disconecting my bat but it doesnt work... lets see the vacuum tomorrow... thanks...

 

Hi

I have noticd the same thing. I have a 09 Jazz ge8 manual (south africa). i have a very long, steep driveway. if put into neutral and rolling down the driveway, the rpm's go up a bit, and when the car stops at the bottom (still in neutral) the rpm's go back down. It has done this since day one.

 

hi again... today when i start up the cel come up... i scan it and it got this code....

p1157 Air Fuel ratio A/F sensor ( sensor 1) line high voltage...

anyone??? what does that mean???

thankss

 

hi, my fit and my dad's civic, both '09, do the same thing. so im guessing its a thing Honda made the cars do for safety reasons when going downhill. idk...im just making a guess

 

do you have a test pipe?
