Audi 90 20V Sport
Discussion
So there`s this guy selling an Audi 90 20V sport and it looks nice in the pics.However speaking to the owner who has owned it a year I was told it has a misfire.He told me it had one when he bought it.I said what youve been driving around in it like that for a year.He said it was only slight when he bought it and if you know anything about these engines it probably just needs some leads.Its a cheapish car at £800 notes but im thinking if its only the HT leads why drive around in it for a year and not change them ?

Because it's an £800 banger? Also depends if it's a bad misfire, or just slightly hesitant under certain throttle conditions. Sounds pretty reasonable. Like 300bhp/ton says, it depends on the misfire. If it's barely noticeable, only shows up when the car's cold, or whatever, then the owner would ask himself "Do I spend £40 on a new set of leads (plus a lot for fitting, assuming he's not mechanically minded) when I don't really notice and don't really mind?"
Seems a waste of money for a minor issue on a cheap runaround, so fair enough.
What else could be causing the misfire, other than the HT leads or the plugs?

£800 quid for a 90 20v with a misfire?
Thats very pricey.
offer £350 and if he doesnt take it walk away.
I've owned 2.2E 90, Audi Cab 2.6E and a 2.2E Coupe Quattro from this era, the misfire could be a dropped valve, or a vacuum problem, or an injector, or an ht lead, or the fuel injection system.
Then you'll need (within months) suspension bushes, cambelt, rear calipers, exhaust, and at some point the heater matrix will burst leaving you to remove the dash to replace it or blank it off and only have cold air.
Seriously, I'd look elsewhere.

Thats really where im coming from.1st you need to try and diagnose if its fuel or electrical related, I would expect electrical as being more common, but not the only reason. Then it's a process of elimination from leads to plugs, coil, distributor, ECU even.
I have a £750 audi 90 20v quattro sport i bought 18 months ago. Better than you would expect. But £800 is it worth it? In my mind yes but i like them.
Took me 9 months to diagnose my intermittant fire, as knock sensor.
HT leads, i replaced two on mine, open the bonnet in the dark and you will see if there is any arcing.
Vac lines get dry and brittle and they will generally give you a dip in power.
As stutter especially if it runs lumpy/intermitant to 5000rpm then OK asfter will almost certainly be the knock sensors (two on this car)
The Hitachi injectors a weak point and at age and mileage cleaning or upgrading for the popular bosch ones makes a world of difference. But not cheap dont expect change from £200, but netts 8-10bhp.
Check the spark plugs as well, they dont need a lot of torque and can work loose.
Despite the age these cars have onboard diagnostics, you can make your own blink code reader for £3 from maplins easily. Or a garage with a old serial vagCOM could scan it. Its in the footwell.
Working these can develop good power, christ 034motorsport make and off the shelf turbokit for these. Even in standard trim quite entertaining.

price wise, £800 seems a bit steep if its missfiring, is it a white one by any chance in North England?
With a missfire, which could be a few things expensive i would be loking at 400-500.
Other really big note is parts some bits you cant find for love nor money (i am there). But there are a lot of 7A fans out there, myself included.

Depends what he means by misfire. I've got an 80 of similar vintage which 'stutters' at certain rpm bands under the right conditions. I've learnt when its going to happen and how to drive around it so it doesn't bother me but could cause a new owner issues (not that I'll be selling it)
Ah it is "that one" Nowt wrong with ones 
the sports were rarer thus still fetch more, only available in white red and black. Most were red. They were rare and amoungst entusiasts fairly desired.
The white one had non rusty wings which is a rariety. The sports are colour coded, have a thinner body trim, lower and stiffer springs forgeds wishbones, quattro jaquard interior, forged front wishbones.
I would contemplate a FWD to match my quattro but already struggling wiht 3 cars 4th would mean a very unhappy missus! Arguably the quickest of that era cars excluding the S's. 7sec to 60 and the engine is a peach, as long as its not misfiring, quicker than the quattros in acceleration, different ratio box as well. ~Mild teaking makes them a better drive than you think.

Said car has some interest on some other audi sites as well, i would expect it will got for £500 personally.
Is it worth fixing, if its £500 then there isnt much lost in punting it on again for the same. One mans poison and all that.
