Hi, I have a Rover 400 si :eek: & I have a problem with the throttle, it's fine with ordinary driving but once I get stuck in traffic after about 5 minutes the engine idles at about 2500 revs ( I can get it down to normal revs by blipping the throttle but when I start driving again then stop it's back up to 2500 revs ) it's not the throttle cable I've removed it from the throttle mechanism and it operates nice and freely.

Has anyone had a Rover with this problem, if so what was it & how much did it cost to sort out.

Regards.

P.S BL**dy cars
 
One common problem is the plastic throttle body distorting and making the throttle stick. This often happens if an induction kit has been (badly) fitted, or if the OEM hose clip has been replaced by a jubilee type clip and over tightened.

Another possibility is the idle control valve is sticking.

I had this on a 620 ti. I had to replace the coolant temperature sensor, and then it stopped.

Cost £6 for the part from Unipart (PWRPETS134)

Someone else has mentioned the coolant temp sensor, was it easy to fit ?
 
yep...

Just drained all the coolant, and replaced the sensor, filled up the coolant, ran engine at idle (and sometimes a bit of revving) with the cap off the coolant expansion tank for a while to get any air locks out.
I had to do it 3 times, the first two times I did it I used a second hand CTS that was not working in the first place.

was quoted 25 quid by an independant garage to do it, but thought I'd be able to save some money and do it myself.
