Mis fire 5 years 10 months ago #185666

Mgtf has developed a misfire
Engine management light does not come on but the misfire is only really there when not demanding fuel or accelerating and more noticeable under 70 mph

Any ideas? Is it drawing air somewhere etc?
I am going to change the fuel filter at the side of the engine anyway, but if it's not this........

Cheers in advance.

Could this be similar to a few folks on here with corrosion between the coil pack and lead . A neighbour of mine who had the same miss recently on his TF had changed his plugs and never gave the connection between the plug lead and coil pack a glance . The corrosion on the lead was the cause .

Yes I had a misfire the fault code came up like this...misfire on number 1

Changing the coilpacks around changed the fault shown to misfire on cylinder 3...thus showing me which coilpacks to change.

I had the same issue some years ago.
Pulling the plug leads off caused a lead to just fall apart, so a set of replacement leads sorted out the problem.
