Lumpy when pulling away for first minute or so....

[lyceum]

Hey all...

Hard to describe, but when I first pull away in first and second the engine sort of jumps as if its dying and then coming back suddenly, so you end up kangarooing a bit. After a few moments it is fine.

I have also noticed that if I give it a few revs, say 1.5k to 2k revs just after starting, its not so bad.

Wondering if its something I should be worried about...

Cheers,

Tom

condensation inside the engine. maybe a slight head gasket leak? or core plug.

 

[lyceum]

Really? I've got no other indication that there could be a head gasket issue, runs sweet otherwise. What do you mean by core plug?

 

[vngtx]

its a metal plate that fits into the side of the engine block or head, theyre from when the engine was cast. stop water getting out. any sign of a water leak?
could be coil pack, fuel filter, or just overfueling.

ok cheers man. Got a feeling could be a coil pack starting to go. Seen no evidence that they have ever been changed and its on 82k. FSH, so think plugs and filters should be fine but may replace for peace of mind.

Hate to say it but sounds like what I had in my old Fiat which ended up being the head gasket on the way out. Check your oil and coolant levels, if the head gasket is on the way out it'll be consuming lots of either or both of those things.

Could also be a dirty throttle body.

Mate mines done this from day one,i just leave it warm up for a lil while before i drive off. Ive hard everything checked no end of times and nothing has ever been found,i think its just one of those things with these engines.

Mine does it too, lumpy for the first five or six gear changes then its fine afterwards.

I have had to replace three coil packs in four months and noticed a tiny bit of oil on one when I replaced it, could be related to that ?

EGR valvle sticking? had a similar problem on a vauxhall. VAG it and see if it comes up with anythin, if it does, would be something like exsesive EGR flow.
