OK, so Timbuk's miggy is running somewhat rough. Terrible mpg, hissing in plenum, hair out the tailpipe, EML, and seems to be running on about 4 cylinders. Idle is smooth, runs evenly enough considering all this. He will do the paperclip in the morning, but would like any comments from here as well. (Other than checking the fuses!)

Has it had a hell of a backfire?
-
hair out tailpipe - massive backfire and potentially the box baffles have been blown :o running on 4 cylinders - check plugs for oil and then .....dis pack :(
-
Hair kept on coming outta the back of my V6 exhaust, until there was no more to come out - it's throaty now :D

Pour a bottle of Redex in the tank ;D

Ignition problems:
DIS (as suggested) will explain why two cylinders are out under load
HT leads, spark plugs...
Air/Fuelling:
Blocked air or fuel filter, faulty fuel pump, faulty/dirty injectors...
Engine management:
Any of a number of sensors failing confusing the ECU...
Exhaust:
The exhaust collapse may be un-related, but it could also be that the exhaust is partially blocked
Timing...?
Did I miss anything....?

Bratz voodoo?

Or it could just be that when the exhaust is unblocked/changed, the rest will disappear

2 cylinders out = DIS
1 cylinder out would be lead, plug or injector
2 cylinders out is painfully slow
-
are we any further forward with this - dont see the correlation between exhaust and engine issues....so far :-/
-
Oh dear, sounds like a poorly Omega. :(
2 cylinders out is the DIS pack most likely.
Hairy exhaust means a visit to Vx for a shiny new back box, and I suspect a pair of centre sections.
This is not going to be cheap...
-
My line of thinking was that if the exhaust were blocked the back pressure could cause big problems, esp as idle is smooth.

Timbuk will check the error codes in the morning. He is convinced it is 2 cylinders down, not one. The DIS is Horizontal with a square plug. Remeber the coolant hose from the oil cooler just went last week and soaked the DIS.
He has new center sections, will get cheap rear box if req'd. Pre-facelift 2.5 Estate.

Didn't know that

coolant hoses and hbv failure often causes dispack issues if theres a soaking

Can confirm, he was round this morning, new centre sections, sounds OK on tick-over, rough when he revs it & stong smell of petrol...........

Attention, any newbeis out there, this is a V6 DIS pack...:

Get the back box done first. If the exhaust is partially blocked I suspect the lambda sensors will be providing duff data to the ECU and could be causing all the other problems.
-
No new codes found only the 2 that were already stored 129 and 132 :-?

Yes, I knew that. Didn't know that Timbuks had had a soaking.

EGR unplugged?

Er ....dunno , but these 2 came up a few weeks ago so i'm assuming their not related to current misfire problem, and its deffo only running on 4 pots maximum :o

Put a new dis in yet?

Put a new dis in yet?
Nope, had a good look yesterday morning to see if i could decide which one it was, really didn't want to get stuck in Cov with no motor. Does look like the one in the pic already posted, but i guess they all do :-/ Mounted horizontally with square plug on right hand side looking from above, anyone got anymore pics of the others?

I think there was only 1 horizontal type, with other 2 being verticlly mounted. The spare one I have is vertical one...

Driving with DIS out could kill the cats with neat petrol
