No warm idle :|

[WRCVR4]

Ok
This morning (Friday) i dropped my car off to get some work done (workshop will remain nameless) nothing mechanical/electrical, just body work.

When i dropped it off, there was NO idle issues.
When i ever since i picked it up it wont idle once warm (idles cold no prob)

Of cause they say they didnt touch anything.

What might cause it to idle cold, but not warm ? If i find out its something thet touched, THERE WILL BE HELL TO PAY.

HHEELLPP PPLLEEASSEEEEE

You have a vac leak i'm guessing?

You have a vac leak i'm guessing?

Wouldnt this stop cold idle as well ?

Not sure if this is related, the car seams to go like a BAT OUT OF HELL atm as well, could be my imagination :roll:

ISC tests fine

I have noticed the BISS screw is VERY easy to turn, wonder if this has moved :roll:

1. Remove the ISC connector.
2. On the ISC side of the connector, you will see 6 pins (see picture). A top row of 3 and a bottom row of 3.
3. With the car shut off, take a ohmmeter and check the resistance between these pins: 1&2, 2&3, 4&5, 5&6.
4. This checks the 4 different coils in the ISC that can go bad. If any of the values are GREATER than ~30 ohms (like in the kohm range), then you have a busted ISC and have to replace it. L
5. If they check out OK, then it isn't the ISC
6. Be sure to reattach the connector when done! I don't know how many times I forgot about that.

Well,
1. Checked the ISC when cold OK
2. Idled when warm today (slight hunt (400-900rpm)
3. Reset the BISS screw (2 turns out)
4. Changed the plugs (BP7ES.8) needed doing
5. Idled OK
6. Started No. 2 again :?
6. 3 turns of the BISS screw, will see if any better now :roll:
