Hi all,
I have a '94 Tipo 1.6ie S, ECU is a Bosch Monomotronic MA 1.7 . (full electronic ignition / injection) - 205 000 kms.-
Regular maintenance is done. (timing belt, air filter, spark plugs).
Before last monday, only problem I had was that some mornings, the Tipo won't immediatly start, it takes 3 or 4 attemps. Sometimes, I unplug/plug the RPM sensors (although I know it has no effect... unless maybe electrostatic discharge ? or plug cleanup), and it works all the time (done several times). So, basically, I never had any problems starting my Tipo.
On last monday, My Tipo cut 4 times on the motorway....3 times at 120 km/h, followed by nearly immediate restart, and once at a lower speed/rpm.
I did the "RPM trick", and never had the problem on the return home.
As preventive actions, I did :
- Contact cleaning of the various Sensors (only air, water, RPM)
- Surface cleaning of the RPM sensor
- Change the fuel filter (50000 kms-4 yrs)
- Did a Multiecuscan : no problems on the Air/Water sensors, throttle position seems OK, lambda as well... No errors monitored, but unfortunately, no way to check RPM failures, as it always shows an error when engine is stopped.
My questions are :
- What do you think of this problem ?
- Do you think the RPM sensor (and/or its connector) maybe faulty ? How to test that, except by an oscilloscope ?...
- I'm afraid there is a deeper problem : the coil connector is greasy (all the engine is, anyway ), maybe the coil itself is starting to fail...
- or even the injector ?... (I used once Kent Fuel Gauge 2).
Thanks for your advices
