I know how picky these things can be, will this work? Import Direct Ignition 23-0134 - Ignition Coil | O'Reilly Auto Parts

 

Not sure what they are selling them for, but although it looks, for the most part, like a D2 coil, when they say it fits many other vehicles I get a little concerned.

 

It's $103 and from what I can see from the site it only fits other Rovers

 

Coils were my problem. I took lr201silver's advice when I did mine, and did them both.

 

Misfire all sorted out, was the coil. Anyone that is able to change the coil without pulling the upper intakemust have the patience of a saint and the hands of an infant!

 

You say hot and under load..

Under load means more gas is going in there..
Is the plug fouled looking?
Or is it white on the insulator?

Sometimes valves stick and can cause a misfire.
Look up Eric Burrows and valve and misfire on Google.
