Title: Misfiring/stuttering/running rough - no change!!!!
Post by: eliteomegaman on 10 May 2010, 10:46:54
The EGR was unscrewed & i've blanked it off, re-plugged it & its still running rough/stuttering/misfiring!
Could the egr valve be knackered & how would i know?
All the brand new ht leads are on the dis pack in the correct order & fully attached.
i've also pointed out that when the new plugs were taken off individually there were only 2 that made the revs dramatically change whilst the others hardly made a difference when taken off - what could this point to   :-/
PLEASE HELP    :'( :'( :'(

RIGHT, that has proved its NOT the EGR then.

So go back to looking for other air leaks ;)

Is it better at higher revs?

It's ok on tick over but when driven it struggles through the gears & have only managed to get it up to about 2800rpm but not taken it higher cos of speed limit on road  ::)
Pipes have been checked for air leaks but nothing found  :(
If the breather pipes are cleaned do u think that might eliminate the problem?
This is really doing my head in  >:(

Forgot to mention (might be nothing?) when the engine starts from cold there's a whinning noise which disappears after a minute or so  :-?

Would like to know what this is too, that new Elite I got does the exact same thing.

seconday air injection pump fubar'd. It lives under the passenger side front wing and is there to appease the green brigade. Ignore it or unplug it and then ignore it  :y  :y

Two faulty coils in DIS pack? :-/

I would try and get to someone with Tech2 (who knows how to use it). It will save you skinned knuckles and money wasted swapping parts at random. :y
