Misfiring cylinder it seems... electrical trouble maybe... Sensors OK?: Cranckshaft sensor?; knock sensor?; Ignition coil?; spark plugs(lose)?; maybe one defective (bad contact) connector on one of the above mentioned; timing belt is OK (camshaft gears and crankshaft gear synchronized)?; fuel- pump/conectors- pressure would be where I'd start from( before the cold starting and after-gauge readings)...
I'm not stupid, mate. Had it Examined a couple of times, they found nothing. Also no errors on my own FiatECUScan diagnostics. I only found that the ignition advance is suspiciously high when the engine does this 4500 angle degrees :-) On the next start, the engine behaves perfectly well. Lamba is new, sensor works... What do you mean by "butterfly"?
Eh? Are you using google translator? I don't get a word... ;-) The pot on the throttle flap is ok and the cables are new, because I had a problem with them earlier.
No, I didn't. I solved the problem by selling the car and getting an Alfa 166 2.4 JTD :-) I know 20+ guys around the Czech Fiat Bravo club and none of them was able to solve this. I even sent an e-mail to Fiat, but I never got an answer :-(

@val776: what part of the "exchanged half of the engine in the process" didn't you understand?
You mean the "idle actuator motor". There was no problem with that either. Anyway now I have an Alfa Romeo 166 2,4 JTD and she runs fine :-)
I've the same problem! Did you find the solution? Thanks...

You got problems with injectors or with computer
problem with ignition coil i think...
