Been meaning to get this sorted for a while now, what's happening is my car is running very rough at low speed. It has a very harsh jerk when I either release or engage the throttle when off the clutch st low speeds (approx 5mph), this is the same no matter how delicate I am with the throttle.
Also yesterday I was in traffic not on the brake, clutch or throttle and the car started surging forwards and backwards, forwards and backwards until I interfered (extremely annoying).
Now, this is most noticeable in first gear and first gear only most of the time, BUT it has happened before in 2nd but not as bad at all.
Also let me clear up what I have done on the car since owning it -- full service (sparks, plugs, filters, oil's, oil breather pipe, new exhaust system, cleaned tb, changed gearbox mount)
Also recently suspected a lambda fault as was getting a recurring code indicating an issue "above catalyser 1", after swapping over the sensors week or so ago, the code hasn't returned..
Also have access to MES, which shows no fault
Any ideas appreciated, air leak seems obvious, engine mounts?
