Hi,
I have Fiat Brava 1.6 16v (100 16v) first reg. 2000. The car is maintened always on time, it has LPG stag4 and it ran very well for many years.
The problem started 2 months ago and it's still present no matter which fuel I am using, LPG or petrol. I've putted new plugs NGK BKR5EZ, new filters, new oil, new fuel pump, I've cleaned throthle body(doesn't have step), timming belt is cheked, ecu is restarted couple of times
The problem is visible on the uphill driving, when i release the clutch the car isn't so agile,or live... it first drops to 600, 700 rpm's and then it's all slugish till 2000 rpm's, then it becomes lively again.
But one moment was interesting, car was slugish even to the 3000 rpm's mark, before I first time cleaned MAP sensor.When I removed MAP, It had very small oil film on it, it was cleaned and the car became lively again, literaly on the very first releasing the clutch it started to push strong forward without throtle help, just like before. But after 15 minutes the problem goes back again
So now it's a little bit better situation but still it won't pull below 2000 rpm's.
I've putted new MAP sensor, same thing happens again. It also happens that it just cut's off on downhill, when i press the clutch, the rpm's drop to 0.
There's also one more symptom, the car is running strange on the first start, it has a "jerk" on every 10 sec, but after half a minute it goes away.
I've got fuel trim malfunction p0170 on the diagnostic.
I would appreciate your answers
