Hello,

My Dutch Hyundai EXCEL 1,3L has a very strange electronical problem,
which occurs regularly, but more often since a week :cry: .

During the ride the engine starts to vibrate more than normally (maybe
due to inefficient combustion????), whereafter the CHECK ENGINE light
is displayed. The problem recently occured sometimes without the CHECK
ENGINE light going on as well.

Then suddenly all power flows away, till the speed is near zero, and
after that the engine suddenly starts to run at maximum revs. During
this whole process the engine doesn’t at all react on the accelerator.


The Hyundai dealer tried to remedy the problem by replacing the
crankshaft position sensor, because that had happened to be a weak
part of the EXCEL-series. The repair didn’t help.

Do you know a solution :idea: ?

Sounds like your transmission is slipping. Did the dealer check for
trouble codes? I would think that there would be something stored since
the check engine lamp came on. If so, what codes did they find?
