I have something bugging me and this seems to be the only way I'm going to be at a peaceful state of mind. If you have a boost gauge, please read the following off of your gauge and let me know what you guys see. Turbo guys do not need to help with this because a turbo works differently from what I have been told.

When starting your engine after its completely cooled off (sitting for 3 hrs or overnight) what is your vacuum/boost gauge reading at (edit) when you first start it up?

Once your car has fully warmed up (the fan has turned on twice) what is your vacuum/boost gauge reading at?

You're help would be greatly appreciated in helping me not go insane about a little thing. Thanks alot.

The gauge should read 0 when the motors off. 15-18in of vac at idle.

lol, sorry, I just updated my post.

What I meant was what is the idle at when you first start the car after being off for a while. The cold Idle reading and then the warm idle reading. Thanks alot

bump for current jrsc users....

mines is at -20 at idle 0 when motor is off

racerx159

lol, I dont need the reading when the car is off. I need the reading with the car running cold and the car running warmed up.

ok, let me see if I can simplify what I'm saying.....

Once the car has been off for about 1-2 hours start the car and look at the vacuum reading then, with the car running.

Take a nice little spin so that the engine fully warms up and stop. Dont turn the car off. What is the vacuum reading with the car running now that the car is fully warmed up.

someone please hook me up

cold start idle should be around 1500rpm till the engine starts to warm up then it should slowly drop to around 750-800rpm

I'm not talking about the idle rpm when cold and then warm. I'm talking about the vacuum reading when cold and then warm.

Just went out and checked to make sure.

-20 Cold
-20 Warm

What are you reading?

racerx159

-20 when cold and then after ten minutes of driving and the fan turning on twice at idle I read -22. How long did you let the car sit? How many times did the fan come on, fully warm is when the fan turns on twice, technically

I just turned it on to see where it sat, it was -21/-20. I know that it reads the same when it's warm, so I just wanted to see where it sat cold. Is your charger running weird, or were you just curious as to if it was normal?

racerx159

I was curious to see if the readings I was getting were normal. Maybe the hondata intake manifold is a little worn and tends to leak a little till the mani warms all the way up and seals better. hmmm, any other ideas?

btw, my charger isn't running weird, its a'ok.
