Hi guys!

Just about yesterday after oil and fuel filter change:
-the engine became hesitant building revs
-now the injector light turns on at high revs (cca 3000 rpm+) and I feel a lack of power.

Mention:
The mechanic tooked the ingnition cables off the spark plugs in order to change the valve cover gasket. I hope he didn't broke any cable...

He also managed to brake the electrical connection to ICV (engine turned off) but I think the last one doesn't have too much influence. And I've fixed it.

Thanks in advance for every input!

Cheers,
Cris.
