Irratic Idle
« on: 03 May 2008, 19:07:02 »
Had my Tourer V6 for 2 weeks now.

It's a T-reg.

Noticed idle was a little lumpy when I bought it so found another ICV at Scrappies.

Cleaned the new one out and fitted it on thursday. Noticed a big difference when re-started.

Then I decided to remove the air inlet ram pipes and check the air inlet for cleanliness. Cleaned them out and re-fitted the pipes.

When I re-started the engine the idle didn't seem right. When the car got up to temp it started to hunt up and down from 1000RPM up to 1800RPM repeatedly.

I tried to find if there was a vac pipe off and removed and re-fitted the air ram pipes but was still the same.

One thing i noticed when going to work was that it didn't do it until it got up to temp and then it kicked in.

My brother says it could be the Coolant Temp Sensor

Can anyone help????

I'm baffled!!!!!

If it was ok with the new IACV before you cleaned the breathers then i would suggest that one of the pipes is leaking air.
Trying spraying carb cleaner around the vac pipes etc...to see if you have an air leak.

Had another look at it today cos it's doing my head in.

Checked the vac pipes and 2 are broken away from their bases.

1 goes to the vac accumalator at bottom of air intake plenum and one goes to the sensor on air thingy at back of radiator.

Both have broken from the bases so will need replacement parts or tapped in nipples?
