Wierd problem

I was towing a trailer today so in total weight about 300kg. After i had to pull out and toe down rather rapidily to get past a tractor i suffered a loss of power.

The engine management light has been on ever since i bought the car (3 yrs) and has had no problems.

However i experienced the rev counter flicking from 2500 revs to none and back again for about 20 times, and the immobiliser light was flickering at the same time.

i.e coming on when the rev counter was reading 0.

I eventually lost power completly. So pulled over. turned off then restarted without a problem.

i have done a further 40miles today without a problem, all beit taking it steady.

Its a 2001 with a Dohc engine.

Does anyone have any ideas as to whats causing this?

Cheers

Most likely the crank sensor, located between the alternator and engine block.

The light on all the time is probably oxygen sensor at the base of the exhaust manifold.

As it is a twincam, one of the £20 eBay fault code readers will get the code, and clear it so the light goes out.

How can i tell if it is the crank sensor? is there any tests? Also is it easy and cheap to replace or is it a garage job?

Do a forum search, loads of people have changed them.

The test is usually to cool it down by pouring cold water over it, the problem is cured for a few minutes until it warms up again.

well after it happened i did another 40 miles with no problems
