New problem, when starting the car cold it idles a bit rough and I hear a ticking noice from the electric box on the throttlebody? It runs rough about 30-45 seconds and then it runs smooth and the ticking stops exactly at the same time the idle goes smooth!? Doesn't sound normal to me, is it servicable?

The voltage is pretty constant 14,1v but on idle it it drops to 12,8-13,5v. As soon as I rev it above 1000rpm it goes to 14,1v. So my guess is to take it off and check the brushes and as you said all connections.

So far no fault codes but.... On idle(around 7-800rpm) the voltage is 13,2v, if i rev it over 1000 rpm the voltage is 14,1-14,2v. Is that normal or is the alternator on it's way out?

Forgot to mention that yesterday when the MIL came on the warning light for passengerairbag disabled came on!? I could only turn it off by using the key by first turning it off with key and aneble it again. So bought a new battery today, the old one was alot smaller so wasn't the OEM battery. The new one is 60ah and fitted right in. Fingers crossed!:-)

Well it happened yesterday again but it's probably not the battery. Car had been standing at work fo 8 hours, when I got out it started fine but the idle was a teeny weeny rough. Reversed out of the parking spot and drove of, got about 10 meters and the MIL came on and car went back to idle. When pressing the accelerator nothing happens, it just keeps idling or maybe it went up 50-100 rpm. I forgot to check the temp sensors but will do today, have checked the throttlebody plate but it was nice and clean so no stickiness there. Charged the battery over night and this morning I disconnected the charger, disconnected the + cable and checked the voltage which was 12,7v. Left the car standing for an hour or two and checked the voltage again and it was 12,5v. Temperature was and is around zero degrees celcius. Also checked the alternator yesterday evening and was a bit worried at first. On idle with lights on I only got 13,3v, with lights out 14v. Tried this mornig again but reved the car to around 13-1500 rpm and got 14,24v so alternator seems fine to me.

I did measure on the battery terminals, I had started the car, driven it out of the garage and parked it on the driveway. after about 15-25 min I checked the battery voltage. My code reader(Torque on my Android phone with a bluetooth OBD unit) does do live readings but why check those temperatures?

The car starts easy with the battery, only thing I have noticed is that the idle is a bit rough the first couple of minutes. Will buy a new battery tomorrow and I'll check the alternator too.:-)

Thanks, i have checked and cleaned the connectors but did not think of the throttlebody and plate. Will give it a clean aswell.:-) I checked the voltage of the battery with engine off and it shows only 11,93v!? I'm thinking that this might cause the MIL light to go on? I think it's the original battery so it's pretty old.

Has happened twice now, can turn it of with my OBD reader but seems to be a problem with the throttlebody!? Any ideas of what is wrong? Car is from 2004 with 70hp 1.4 gasoline engine. regards Peter
