hi, sorry to raise an old post back from the dead, and dunno if am posting in the correct section. I have recently bought a 156 1.8 ts v reg. From cold startup its like have kangaroo petrol and virtually no throttle response and once its warmed up this problem is gone. Then while driving if am trying to get over 4000 revs (regardless of gear) its as if theres a limiter on the car and it wont go over 4000 revs and just seems to lose power until i change gear, then the same happens again until i change into a higher gear again!
I dont know if the two problem are interlinked?
I changed all eight spark plugs on day of purchase, cleaned maf sensor, cleaner air filter (previous owner down the line fitted one of them daft green cone filters!).
Am waiting on lead to connect to alfa diag and fiat ecu, tried a bosch KTS on it and cudnt connect?
Any help would be greatly appreciated
