alright well my car never idled wrong till this week rpm's jumping from 1 .5 to 2 over n over, n i smell gas at some times and the car cuts off at times when i stop, do i need a new map sensor & would that take care of everything? thanks

 

?

 

could be one of a million problems.. lol check for a vacuum leak or leaks between the head and intake manifold or the TB to the IM. most common problem.

 

my friend says i need a idle air control valve, & sum mechanic told me i need a new map sensor...

 

are you getting a CEL at all. i would really check all your vaccum lines, and make sure that nothing came lose.

 

does it sound like you could hear a leak..? like hearing the cams slap etc.. cant really explain it..

You could always spray a mist of water at the Intake manifold, and header to see if thats the problem area. More than likely if it was your map your car would be almost undriveable period, and you would be throwing a CEL code.

If you are check the number.

 

all i know is i can here the intake suk alot & i dont really know how to chek on the CEL lol ima noob but yeah ure right i know if it was the map sensor i wouldnt be getting any gas... what do u think replace the iacv?

iacv is expensive if thats not the problem... do you have a check engine light on???? spray carb cleaner in the area of the intake manifold and throttle bodie if the RPMs shoot up you then know there is a leak in the area. if not. your iacv may need to either be replaced or cleaned... umm checking the year...... what motor is it???? i cant find it. if you have a fast idle air controll it could be that but that all depends on what year and motor. it could also be a sensor in the intake area. ie map/iat or such. i had this one site on hand that showed all the reasons why a honda would have a wack idle... im sure there are million+ threads on this topic. good luck. in the mean time i will search for the site for you.

 

Sounds like IACV to me, I've had a few act up before I got any CEL. Though that wouldn't explain the fuel smell.

 

anything new?
