Idle problem

[mox]

This morning when getting to work I was feeling the car 'weird'

When I parked the car the idle was going from 400rpm to 1100rpm and vice-versa

I had no performance loss with the car

I think it's a 'common problem', maybe I need to change the wiring or the spark plugs

The car have 50000km only

Anyone have an idea or something that I should verify first ?

Thanks

above all... check your temp gauges and o2 sensors.. those are probably going bad.. check that out first

Check all the vacuum lines for leaks. Also, check the big tube that runs from the air filter box to the throttle body for cracks. This can create a large leak of unfiltered air coming in to the engine and the computer can have a hard time trying to adjust for this, causing the symptom you describe.

Went back home to lunch, I had no problems with the car
Got back to work with no problems.. got back home with no problems

We'll see if this problem happens again tomorrow morning
