Hi y'all.

I guess I know the answer to this but want to run it past you all anyway...

I've just suffered the heater bypass valve failure that leads to coil pack failure thing, but after replacing both the car still misfires incredibly badly under load! Idles perfectly.

About 6 months ago I had to replace the rocker cover gaskets and the plug lead stem thinggies must have been totally immersed in oil for months.

Has this oil-soaking damaged my plug leads? Is it possible to replace them without taking the engine out  ?

I'm on a budget and have found new sets of leads for circa £30. Will these be OK? I've seen sets for £300!

What are the chances the new coil pack (non VX) is faulty?

Any tips, advice, ultimate answers?

It's a 2.5 V6 S-Reg (1998/99)

Cheers,
S.

i would say yes it has, however, missfire under load could be diss pack. i would change the leads first imho. easy enough to do but rather fiddley.
