View Full Version : Odd Idling... Hesitation on 2nd Gear?

Let's just start with this:

1 Week ago, bring my car to my local dealer. They 1) Removed the Heat shield around my Cat cause it was rusted and was flapping at High RPM's. 2) They tightened my pulley belts, and though they make a noise it can't be heard unless you stand in front of the car 3) They did a Valve Adjustment, no more tapping noise and quiet as it can be with my Super Charger.

So, I pick the car up that night and they leave me a note. Said my Oil was low (had changed the oil two weeks ago, so that was odd) and the pressure in my engine was low as well. They didn't check that after doing the Valve Adjustment. So yeah odd right?

Anyways, I am driving back home. Car runs fine, but I noticed my Idle was changed from the normal 1100 RPM's warm to like 600 RPM's. I figured they did that cause it made it run better, dunno. Car sat for the entire week cause I carpool.

This weekend, I start driving it again over 50 miles. 1) Car feels like they put the idle TOO low, like it's gunna stall You can barely feel a stalling vibration, but it's there. I noticed the difference immediately. 2) When I braked a few times, I noticed my RPM's dropped immediately to like 100 and then shot back up to the new idle speed of 600 or whatever. And pop the hood, you can see the engine shake a little, did not do that before the valve adjustment. Using the throttle, I push until the RPM's hit 1100 and it stops shaking and sounds like it was before. Does it need to run higher cause of the S/C?

Could they have messed with anything? I noticed there is some slack on the throttle cable (see pic below), does that need to be adjusted? People say it's normal for low idle in honda's, my old 2003 never idled this low and was always around 1100 like the car was before the valved adjustment.

ALSO, when I change gears from 1st to 2nd, it feels like my car bogs down immediately and then kicks back in. I try to shift that s*** as smooth as possible but it's just annoying. All the other gears are fine, but yeah, 1st to 2nd is always a little rough. Any idea's? Or is it just my shifting? lol

Here are a few pics:

Car is completely warmed up here, I let it warm for 15 minutes.

I there should be slack in this cable, but why does this seem too much slack?

Is that my cruise control cable? There is a LOT of slack in that cable. I could put my oil cap under it before it moves the throttle before it picks up the engine power.

A lot of questions, I know. Gotta relearn my civic, and I am new to Manuals & SuperChargers. So bear with me. Thanks.

that idle looks normal. its supposed to be at 700-800. u have a boost gauge? idle warm vac is like -22in. make sure its there.

have kpro? see what tps says with no foot on the gas. if you had it scaled before you might have to rescale it.

No K-Pro. Supercharger is Jackson Racing, so it actually comes with a ECU Mod called Powercard that connects to it (noob so I might have described that wrong).

No gauge, is there a way I can check that? When they did the valve adjustment, could that have fucked up the idle vac?

when they did a valve adjusment they could have nicked or left a hose loose check it out it might be something as simple as that

Checked the hoses, nothing seems to be loose or not connected. And yeah, I could drop it back off and complain but they will of course deny they did anything wrong and will charge me to fix it. They normally do a good job, but it could be something simple. I don't see too much of a loss of power tho, so I dunno.

Also, I read somewhere that the belt could be tightened too much and thus affecting my performance or idle. Since I can hear the pulley making a slight noise like rubbing, and the pulley moving a little more slowly than before, perhaps that? Below are two pics, could someone let me know if what I took a picture of is where I can adjust the belt? This one is different than the slider I am used to.
