    Cam/lambdor sensor?

    Well guys hoping to get this problem fixed once and for all with your help. Now some may recall me and lee_h did the diagnostics on my 318is m44 and it brought up one of the sensors (which escapes my mind right now) anyway I was wondering if or of these was the fault I'm looking for.... So a brief history

    Car since I had it has never ever had a engine fault really always ran superb! Anyway it started to show signs of flat spots when accelerating in lower gears (probably all gears but more noticeable 2nd, 3rd)
    Anyway a couple of months back I went out in the car and the flat spots where huge and at one point I tuned around I go home as the car wouldn't accelerate past 2500rpm at all foot down in second gear!
    Now I thought then that the cheap exhaust I bought when I got the car (nearly two years and 50k ago) had dropped its baffles in the cat or back box ad wasn't letting any gases escape... So I managed to get it home and went inside had a cuppa and went out took it down the road.
    It hesitated like fook in first sat at 2500 again then shot of normal speed! And it's been fine since.... The exhaust sounds no raspier than normal and doesn't rattle....
    Now the flat spots are still there like before it happened like just slower parts of accelerating right up the revs

    So can anyone tell me what caused the big issue? Are they related? And are the flat spots down to a sensor you think?

    Hope someone can help please want to get this car sorted now so I can decide which direction to go with it

    Niall, if thats the same exhaust change it mate. Ive seen Loads of these with blocked exhausts, they collapse inside. If its blocked it will cause a massive hestitation and if it gets too bad it can cause head gasket issues.
