New to Alfa 147
My 147 2.0 TS Selespeed 2004 recently started to have several minor problems symptomatic with misfiring or blocked injectors or leaky spark plugs/leads. I will describe the problems below and help is musch appreciated.
The engine starts without problem and after the engine warms up sometimes the engine hesitates to rev up. Once the revs get above 2000 RPM the engine response become normal. During this hesitant period I can hear the engine pinging (knocking) and then suddenly the engine revs up as if a turbo kicked in. Sometimes the it behaves as if one cylider is not firing. This problem sometimes appear during idling and I have seen the engine rocking when this happens. After reading some help in this forum I disconnected the MAF and drove it and the problem was still there.
