Technical engine shudder

[aaronwilson11]

Owned my fiat stilo 1.2 i 16V for half a year and up to date no faults.

Within the last 2 weeks, my engine has started to shudder. Very lightly though and when trying to explain to my girlfriend she can't feel a thing.

But its not right

Between 3rd to 5th gear especially 3000 to 5000 revs the engine shudders, then when over 5000 pretty much nothing. It definately something to do with accelleration.

Cheers for any advice!

Might help if a dealer took a look for any codes stored in the ECU, but that would cost you. When did the car last have a service and were the exact right spark-plugs fitted? Could be a coil pack problem starting or a dirty throttle body, can be expensive guessing and using trial & error techniques too. Does it use any oil / water? Assuming here that the air filter is in good condition....

I'd say coil pack is a good place to start as one of these should really be carried as a spare anyway

Lots of info within Forum on how to check these.

Would the word 'Hesitation' describe it better out of interest? Is it deffinatly a shudder

Re: problem foundengine shudder

After going into the engine, removing the air filter, I've established the problem!

As the air filter screws have come loose, the box has been banging against the top of the spark plugs, snapping to of the cable connections making them loose.

I need to know the name as I can't seem to find it on google, I need the new socket that sits over the spark plug where the cables plug into!

Does any body know the name of these ???????????

thank you

Coil

Nope ..he asked about what he needs to sit over a plug ie.. a socket..

PLUG SOCKET..fit extension to it and remove de plug..at least I think thats what he wants..

Coil just need a 10mil spanner..

As Morten suggests, I think the OP is looking for a single coil-pack :idea:
