Rough Running 156 (2.5 v6 1999)

[comdiver]

Now 92k on the clock and with a Haywood & Scott exhaust, Autodelta carbon intake and a cat by pass on it has after some time started to run rough. Within about 2 mins of starting down on power and misses & once warmed up it has quite a noticeable hessitation at about 5000rpm in all gears.
Have cleaned out the filter and intake system as well as the MAF meter and checked out the front bank of coil packs and plugs but to no avail. Just wondering if anybody would have any ideas or if any of this would show up on a fault code reader.
Thanks in advance, Brian.

I suffered from the hesitation, as you described, it's like someone has their foot on the brake pedal after about 4k revs.

A new MAF sorted it out.

MAF normally causes these symtoms...
GTV's seem to go for a pass time...

Oh well looks like a new one it is then.

All done and working ok now, new MAF under the bonnet. Thanks guys.

It seems like a new MAF is just part of general wear and tear in the wonderful world on ALfa!
