Hello dear,
I have Fiat Linea 1.4 8v 2007 y. petrol and TNG on 135.000 km. I am a first owner. I have a problem with starting engine. ONLY FIRST starting an engine (after 4,5,6 hours) it's very hard... If try to start on first time it can be 12-20 seconds, and maybe not start. BUT... If I turn on the key to start, and go back in 3-4 seconds, after that, immediately startting an engine is OK. In next 3 or 4 od 5 hours all is good. Starting BUM-BUM. But after that time... Again the same problem.
No problems on diagnostic (Delphie) in service, no error codes in ecu...
I try to take off sensor O2, sensor temperature. Changed MAP sensor, plugs, timing belt, water pump, line belt, oil, oil filter, air filter... Try to starting with another battery... Always SAME problem.
Anyone who can help me !?!?!
Tnaks in advance.
