Hey guys, I’ve owned a ’94 80 2.0 litre manual, for about 6 months and it’s developed an infuriating fault and I’m needing any help and/or advice I can find. So here goes….
It starts up fine and runs sweetly for any given amount of time, until engine suddenly dies without warning. I’ve been travelling at speeds between 20-70 kmh when the revs suddenly drop to nothing and the engine stops. Sometimes it restarts right away and may not do the fault for a few minutes, other times it starts but higher revs can only be maintained by constant accelerator pressure, etc. At times you can drive it for a week and its sweet – till it once again dies. A couple of times just as you start the engine the revs drop below normal idle range and revs are ‘roughly’ kicked back up to about 800 rpm - this doesn’t always happen and I’m not sure if there is a connection between this and the fault.
What I know:
1) The ECU reports no error codes.
2) The fuel pump is new and was replaced less than 2000 km ago.
3) Coil pack unit is new - it was installed in the hope that it was a weak spark problem, but the fault occurred within minutes of this.
4) Fuel pressure in the system has been tested and is fine.
We’ve been thinking it has to be an electrical issue, possibly a loose wire or connection. We’re in the process of removing all connections, cleaning and reconnecting all plugs, but still nothing.
Any ideas or has anyone had a similar problem with theirs? Could it be due to a faulty relay in the system? Oxy/lambda sensors? We bought the car from a dealer and I’ve heard that sometimes they have the engine steam-cleaned and this can cause probs- could this be related?
As you can image it is an absolute pain in the a*** and I’m pretty desperate at the moment.
Any advice ideas will be most appreciated. I love this model and it’s a fantastic car to drive – except when it does this sort of thing.
