Hi,
I'm new to this forum and I hope you can help me with the following problem of my Fiat Punto 1.2 8V (2000)
First of all I'm from the Netherlands. I'm not familiar with the technical words in English but I hope you will understand the story.
My car starts normally, but when I exceed approximately 2500 rpm (it's a guess, I don't have a rpm display) the engine stalls, until it drops beneath 2500 rpm, then it accellerates till 2500 rpm, then it stalls again and so on. The problem is the same when I accelerate in the neutral gear.
This started 2 months ago, first only incidents but it became worse.
The fiat garage examined the computer, but after resetting it, they didn't find any error codes. Head gasket is ok.
I replaced the TMAP-sensor, without any result.
The ignition coils seem to be ok, same resistance values for both of them (low and hight voltage contacts).
The car display doesn't show any engine problem, no blinking light.
Spark plugs and cables, air filter, oil filter, oil and the rear end of the exhaust have been replaced 6 months ago.
What seems weird to me is the following:
I took the cable of a spark plug.
I attached a spare plug on that cable and held it to a metal part
With the engine on I could see sparks very clearly
When I accellerated the sparks disappeared completely
I did the same with the other cables, same result.
Is this normal?
Any suggestions are welcome!
Thanks.
