hey guys, to start off iv been folowing just commodores for the past fue years but this is my first post so go easy on me if im posting in the wrong section or something.
iv got a vz calais (190) wich has recently started playing up, under full throttle at about 4000rmp the engine starts to cough and splutter. still reving up but the speed of the revs seems to stop almost like a flat spot and then continue to climb. its most noticeabull at 4000rmp but does hapen between 4000 and 6000 intemediately.
i only started to notice this after putting a full exhaust system on my car (x force extractors high flow cats and 2 1/4 twin) my car also has a cpr6 manifold on it and the car hasnt been tuned yet... (i never noticed it playing up when i just had the cpr6 manifold and standard exhaust)
basicly im just wondering what people think of this problem and weather a tune could more likely fix it or if they think i may have engine damage..
any responce would be appreciated
regards josh
