I have an 82 Ferrari 308 GTSI Fuel Injected. I recently had the timing belt changed and rebuilt the first head with new valves and new guides. I also replaced the clutch with a new one, new spark plugs and wires. Since then my car has not been running good. My thoughts are that when the mechanic replaced the timing belt, I'm guessing that there may have been 1 tooth off time. Also I believe that the fire order was wrong because I lost some power and he also touched the flywheel while working on the new clutch replacement. Since then, when the car is warm, I am unable to start it without putting my foot on the gas as a carburator car and not as the fuel Injected car I have. Furthermor, the exhaust manufold becomes bright red and hot enough to melt the aluminum skirt cover. (I also lost the famous Ferrari Wistle sound from the air intake :0(

). Please any help is kindly appreciated on any of the problems I am undergoing.
