Car bunny hopping a little low revs 30/40/50 3rd 4th and sometimes 5th.

Why could this be? Never used to do it?

Seems a bit juddery... only when im cruising, keeping a steady low rev speed etc.

Its strange and could be coincidence but i think it gets worse when i use lower quality fuel? eg tesco.

What engine? I had this sort of problem with the car badly misfiring and wanting to stall. Ended up changing the Air Temp sensor and it's fine.

It never cuts out or stalls, just jumpy when low revs, and low revs climbing slowly.

Mine jumps a little at 2000 RPM i thinks its back pressure in the exhaust mayb wrong but every time ive had the exhaust off and put back on its fine. I may put a sleeve over the joint to stop the exhaust leaking.

Interesting, i might get under the car and check for leaks, its been smelling of petrol more than usual recently but i assumed that was just cause of the decat...
