Spark plug issue?

[k7lsy]

Hi guys,

Just got spark plugs replaced with the recommended Motorcraft plug AGSF32WM from the following seller:

I've got a misfire problem when under load - tick over and light to mid loading is fine.

Have i bought the right plugs because the price seems very low (£8 for 4) compared to other places where i've seen them for sale at £30 for 6.

Any thoughts?
Cheers
Kenny

Plug gaps too wide, set them @ 35 Thou.

Kevin - thanks for that suggestion. I'm going to test that out this weekend.

As the recommended .40 gap is not working :-(
