Greetings, I finaly found one driving coupe in good condition in my country. It was 1.8 but engine got replaced by current owner because 1.8 was dead(no regular servicing and had poorly installed LPG system). Current engine is 2.0 16v with just around 110k miles. Current owner is a trusted person. He says he didn't drive it after the swap(he started working in some sort of mountain rescue service or whatever it is called on english so he drives a vehicle provided,serviced and refueled by goverment) and he says car was sitting almost 1 year,but was turned on regulary. Now his mother is driving it sometimes,in this case she went on vacation with coupe so that I could check it out. When we met, I was able to confirm that it was in good conditon. It has some rust on it but it is nothing mayor with no structural damage,mostly wheel arches and right side of the trunk. What does worry me is that it had injector light lit on the dashboard and it does not want to go away. It idles pretty rough,but the engine speed is steady at around 800rpm. It drives great though,throttle response is awesome and there are no hiccups or uneven power distribution. I told the seller(he doesn't know alot about cars,so he called his servicer and the servicer said that the ECU probably wasn't reset after the swap...) it could be some sensor like MAF or Lamda,but that it could also be something major so we made a deal that when his mother comes home in 5 days(she lives 400km away from me),to take the car to diagnostics and report back with photos what it shows.What are your expiriences with this problem? I couldn't find anything specific on google.Thanks for your help in advance.
P.S Forgot to say that the car also has brand new exhaust(changed because previous owner had some fart can with no catalyst),so my first guess is that Lambda is not connected.

Bump

Hi Dorian, the injector light could be anything electrical. Needs to have the error codes checked.

Good luck, sounds like a decent car

Hi Dorian - got some injector light issues myself and as Morrison says the general opinion is to get the codes read before starting to buy parts as it could save a lot of time etc.

By the way just come back from 2 weeks in Croatia - a week on Havr island then a week in Split. Really enjoyed it - nice people, good value and great weather. Sea urchins not too friendly though and stood on one when snorkelling so now have a foot infection Don't run this sort of risk in Warrington

Codes really do help focus your attention, as in my case I had connected to sensors the wrong way round and it the light was on, however, codes said lots of things and it took a while to find the actual issue. codes said lambda faulty until i connected the other two correctly and the lambda fault disappeared too.

So that will teach you not to drink high strength lager before doing coupe maintenance

That reminds I must put a lock on the beer fridge in the garage

Hi, quick update. There is 90% chance its lambda because guy says it came on after the exhaust change(when I checked the car the first time, I saw it had new exhaust up to the manifold).Can I fit it from let's say punto 1.1,tipo 1.6 and such cars,since I couldn't find it for 2.0 16v? Btw guy was in Italy on rescue mission and he is comming back to Split in a week,so then I will be able to connect it to diagnostics.

I bought this one...
