Title: TC erratic idle and cut out
Post by: kmason8282 on 08 April 2011, 23:11:25

My car has recently start to cut out whilst driving.  The symptoms I seem not notice are as follows:
1- TC light comes on
2- When I slow down I notice the car struggles to accelarate.  I think this is called 'limp mode'
3 - Also notice idle counter erratic at standstill, from @700rpm to 1200rpm then back to @700rpm.
4 - Electric management system light comes on
5 ... shortly after the car will cut out, loss of power throughtout.

...leave the car turned off for 3-5 mins then the car will start again yet the same symptoms arrive shortly after.

However ... recently used the car and had no problems for 20 miles or so and then today went on a very short drive and the same problem arose again. Car cut our four times before I got it home

My cam sensor has recenlty been changed as my car did start to cut our every now and then and via tech2 error was low rpm hense sensor change.

It can be narrowed down a bit. 4 pots don't have TC  ;) ;)

Electric management system light comes on

The fact that the E.M.L. is on means the car is trying to tell you what is wrong, get the codes read.

Are you sure the cam sensor was replaced, not the crank sensor?

I'd be checking the Idle Control Valve first, giving that good clean, making sure its opening and shutting correctly  :y
