Irractic Idle - Cleaning Throttle Body

[aussieboxy]

From what I can tell this is a common problem with our cars & is very easily rectified.

With my 2000 2.7 the idle would vary from anywhere between 300 & 1300 and putting on the aircon made little difference.

I found out about this fix from a Rentech forum which was very useful.

Below is a brief runthrough on how to clean the throttle body.

1. Place the car into service mode with engine hatch open. You can clearly see the throttle body as marked in the pic

2. Remove the black induction tube by lossening the hose clamp at the throttle body end and then the other clamp at the other end which connect to the airbox wher the air filter is located.

I found it easier to just reome the tube rather than just the end near the throttle body.

3. Next remove the 4 bolts holding the trottle body to the intact. They have an allen head.

4. Remove throttle body & place on top of engine. I put a old towel underneath it to catch the excess cleaning fluid.

5. Clean the trottle body(both sides) with carb cleaner. The pics are mine before cleaning.

5. Replace the trottle body with the 4 hex bolts. Careful not to overtorque as they are into a metal sleve in plastic. Just hand tight then nip them up.

6. Replace intake tube. It can be a little difficult to get the end back on the throttle body so I used just a little WD 40 or CRC on the inside lip to help it slip back on.

7. Tighten both end clamps of intake tube & start her up.

8. Replace engine cover & return hood to normal position & your done.

Quite easy to do and should only take you about an hour or so from do to wow.

If you have any questions PM me.

Good luck.

Good work and thanks for the write up and pics. I've got to do this, having the same idle issues.

Great right up!
I'll be doing this this weekend.

2 quick questions:
1) did you dry the throttle body after cleaning it or did you let the cleaner evaporate dry?
2) when cleaning it with the fluid, did you just let the fluid run over the surfaces or did you scrub the surfaces with a brush/cloth?
