GTV 2.0 T spark missfiring issues
1st post on here, new alfa owner!
my 2000 gtv 2.0 16v t spark has developed an issue with the engine..
when moving up through the gears it stutters some time at lower engine speed, but once you reach 4000rpm to 4500rpm is missfires more hevily and the engine wont increase rev speed. Also possibly feels down on power at the lower revs
Took to a garage who ran an electric diagnostic (not sure how much i trust their systems) and it did not shows any errors. They changed the spark plugs with the platinum plugs, all eight but this has not solved the issue...just lighted my wallet by £200! Theiving b@stards!!
Am now thinking that it is not a connetion issue, but perhaps more related to the ECU and fuel/air mix.
Has any one experienced these or similar issues? Its a widely used engine so feel someone must have expeirenced this before....help! dont want to pay more momey to someone who doesnt know what their doing!!
