Engine Mechanical problem
2001 Other Fiat Models 4 cyl Wheel Drive Type unknown Manual 80000 miles
----------------------------------------------------------------
my fiat brava, recently underwent autogas convertion. engine light on when running with gas. code p1171 & 1172, says "above limit". though i refuse to blame the convertion. you see the car has got some long standing problem which i reckon it affect gas to perform properly. firstly, engine tempreture rises quickly when idling, just above halfway, cool down when moving. than gas flow not smooth, hesitation in emission. these happen on both petrol & gas. got a corroded engine sump. after reading some articul, i suspect engine valve, air meter, air filter, fuel filter. injection time:2.80 air flow:7.10 any suggestion?
