AlfaRomeo 156 2.0L TwinSpark loss of power after 4000 revs!
Hi guys! Just recently bought an alfa romeo 2.0L 156 TwinSpark and i absolutely love it! For some peace of mind, and seeing that it has 100,000 kms+, i took it to have the engine oil and filter changed, air filter and spark plugs changed and give it an overall check. Before i did all this i noticed the car struggles to get past 4000 revs but i imagined it just needed new spark plugs etc. now that ive done that, it still struggles to get past 4000 revs. As if there was too much petrol going through or not enough air into the air filter. I know that the previous owner had it stopped for a year or so. Maybe the injectors are full of dirt? I added some injector cleaner followed by a full tank of petrol hoping that would make a difference but it has not. Any ideas as to why this may happen? The car pulls very well from 2000 - 3,500 revs but loses that pull after 4000. Please help!! Thanx!!
