good to hear: getting close

 

would this also explain somehow the staling of the engine?

oke, let me try to describe it:

 

My impression is that the engine stalls when you engage the clutch: the engine revs back to idling speed (ca. 780 rpm) but sometimes it goes down to 500 rpm for about a second, reves a bit up to 750 goes back to 500 (don't remember it after that)  but in the end it stalls

 

I think it has may something to do with the fact that it doesn't regulate it back to normal idling rpm but much lower. May be this has something to do withh the misfiring and the wobly engine: there could be a relation. One way to get around is to put down the throttle your self so that the  rpm stays above say 1200 rpm: in that case it wont stall.

 

I tried also applying the rear breaks to see if it would stall unexpectedly or to soon: I could get it much lower than 780 and 500 rpm was not a problem.

 

So it could be a coil that fails sometimes.

 

Next time i will read out the ECU

Hi All.

 

 

Found a thread that really closely describes the problem I have seen myself last weekend: engine flip-flopping between 750 and 500 rpm twice and than dies, after reading this thread I bet on EGR and one of the coils being bad which causes the bad aidling which makes a bad combination of EGR and a bad coil which is a combination the ECU is not able to handle and that might be the reason that this combi is causng so much grief
