Slight misfire (1.8t manual)
Under hard acceleration my car has developed a "slight" misfire. It's not there all the time however.
I've changed the plugs, but was just wondering where is the cheapest place to purchase plug leads? I may have to change the coil packs too. Thanks. Last edited by IanR75; 23rd July 2015 at 18:06.. |

The most common cause for a misfire on the 1.8 is a leaking inlet manifold gasket Most parts can be found from Mat at DMGRS http://www.dmgrs.co.uk

I've used these to good effect:

A misfire under acceleration is more usually a sign of a tired coil park rather than the inlet manifold gasket.
