HI, I'm casting my bucket into the well of S2 forum wiseness, My daily driver (coupe 2.0 8v) has developed a hesitation / splutter which is proving difficult to sort, so I'm in two minds as what to do with it - sell it as is, or break it for parts.? I've had it over two years now so feel ready for a change - It's a 95 N in kingfisher blue with black half leather sports trim, also has black headlining (non sunroof) What to do ????

Someone on here or Audifans should know what the cause of the hesitations is.
Can you list or describe more detail on the symptoms of the problem to increase the chances of a more accurate remote diagnosis of the problem ?
Anyone BTDT ?
Kind regards.
Well ... it starts from cold no problem, runs fine until the engine temp gets to a 1/4 way up the gauge - thats when it starts to splutter etc also the idle is very erratic - when the engine reaches full operating temp its still running rough but if the ignition is switched off & restarted all is fine ??

I would say lambda sensor first. Also try disconnecting the cold start injector. I leave mine disconnected permanently.
Failing that, start looking at things like, plugs, plug leads, ignition stuffs, then things like fuel filter etc.
Is it single point injection or multi point injection.
My old saloon was single and that needed the rubber boot under the throttle body changing. Although I would say with the year yours is it will prob be multi point.
Sorry I should have said --- well so far I've changed ....
new cold start injector
coolant temp senders x2
plugs, leads
rotor arm & cap
idle air control valve
breather system
fuel & air filters
had tested ....
ecu
lambda
air flow meter
full diagnostic check - agreed there was a fault but couldn't say what the cause is, only " it's an old car & old cars give trouble " ?
