Hi,
I have recently swapped my '98 1.4 Bravo for a '08 Bravo 1.4 t-jet 120 hp.Not yet familiar with the engine.
Lately when starting the car (cold engine, overnight) :
-car starts fine ( first time, every time)
-after it starts the revs climb to ~ 1500 rpm
-then a second later revs drop to ~500
-then up again.. and down.. for about 10-15 seconds.. then it stabilizes around 1500 until it heats up.
There are no stored error codes.
Any ideas what may cause this?
The car runs fine after, it pulls well, mpg is about right, nice idle.
Do these engines have any known faults for this kind of behavior? i.e dirty throttle valve, map, temperature sensors... or something?
The car has covered 120.000 km and has had it's spark plugs, oil, filters and timing belt changed about 1000 km ago.
Help is appreciated.
