Hey guys, FD dies when your trying to park it or coming to a slow stop. It just slowly dies like it cant hold idle or something. I was told it might be the air idle control valve. What do y'all think. And how much would it cost to fix. Thanks

 

someone just told me a vacuum leak might be the reason

 

Is it an automatic?

If it's a manual, do you have the same problem whether it's in neutral or in gear?

 

its a 5sp and in neutral yes or in gear

 

A vacuum leak will cause it to idle higher, not lower.

I suggest you bring the car to the two FD experts in the Houston area, Chuck Westbrook and Kyle Krutilek. They know these cars inside and out, PM one or both of them----cewrx7r1 and twokrx7 are their s/n's I believe.

 

oic, so what can be wrong with it? and i have, they have both seen the car. told me it might be the air idle control valve. so im just trying to get some more input.

 

o sorry, Rx7_Nut13B and his friend looked at it.

 

is the IAC still plugged in?

 

A few things to start checking first:

1. ISC (Idle speed control)
2. Clutch switch

 

i would have to say clutch switch also.

 

ok thanks guys

 

someone just said it could be the vac line. im getting someone to look at it on Saturday. also a friend said after it warmed up it stoped surging.

 

inform me on how the clutch switch would have anything to do with it...

 

The clutch switch feedback, along with other components, is used for idle control.

 

O.o i learn somethin new everyday

 

so heres the check list, anything else y'all want to add.

1. ISC (Idle speed control)
2. Clutch switch
3. Air idle control valve
4. Vac line
5. Vacuum leak

 

What exactly do you mean by 'vac line'? A stock FD has almost 100 of them.

 

i have no idea, i was just told to check all of them

 

a vacuum line or vacuum leak wouldn't do that, it would raise the idle or make it hunt, not make it die. I had the exact same problem with the clutch switch, when trying to move the car in a parking lot, it would die every time i would let the gas pedal go. It is really easy to check and it cost like 20$. Stop searching on the net and start removing that switch

 

alright thanks bro
