The problem my 4kcsq is having sounds similar however
there is no smoke in my condition.
There is a distinct smell which is reminiscent of
epoxy glue. I am not sure if that is a similar smell
to an over-rich exhaust though.

There does not exist the typical "backfire" pop sound
from the exhaust, but a quick thump or two comming
from the intake upon attempting to rev the engine.

Turning the car off and then on again has stopped the
symptoms sometimes, but sometims the car starts up
running like crap too.

I am wondering if Paul's condition is a separate case.

What about the knock sensor, is the light on or
flashing when this happens?
Diagnostic codes in Bently?
20v has CIS-E-III right?
