hi guys, my 156 has an intermittant power problem. when accelerating slowly its not to bad, but floor it and when it gets passed 4000 revs it feels like a missfire, espiecially up an incline. done the usual MAF throttle body cleaning, but no joy. its not all the time though. if i drive it flat out for a while it seems better, but then when normal driving resumes so does the problem. also it takes it time starting first thing in the morning, rest of the day its fine, symptom of non starting is, turn the key and engine will spin over with no attempt to fire, turn off the key and start again, it will start first time.
cheers in advance

disconnect the maf & see how the car drives, if better then the maf is suspect bad

if not difference then you'll need a diagnostic session to figure out whats wrong.
