Can the lamba sensor "get better" without any repair? I had all the injectors replaced in my 1.6 sx and found that the injector light was on permanently, even when coming off the accelorator, though the car ran ok. I just felt a slight lag in acceleration. My mechanic pal thought it could be the lambda. I always have to wait forever for him to do the work, but he is a diamond geezer. Now all of a sudden, the warning light has disappeared. It comes on very occasionally for a few seconds only. My question is, could the lambda be ready to give up the ghost? Or is it more likely there is some loose electrical connection? I can just see him turning up tomorrow and there is nothing wrong with the car on the surface.

The lambda sensor fault sometimes is intermittent, so yes it could be functionning on and off, this means that you need to replace it, especially if it's been a while since it wasn't replaced.
I'm saying this cos this happened to me, the car would sometimes runs fine and sometimes not, when I changed the lambda sensor it was fine again all the time.
Note: It's good to reset the ECU after changing it, cos the ECU compensates for it and it's likely to keep its temp settings after the sensor change.

faulty injectors often damage the lambda and cat if the car is run for exptended periods with an injector failure. unburnt fuel enters the exhaust system causing the damage. its not uncommon to see the cat glowing bright red once the injector is fixed because it starts to burn all the unburnt fuel that has collected in the cat, the smell is horrible :yuck: . i'd change the lambda sensor

the other day I rev my 1.4 brava hard for the first time until i think it was the limmiter that cut in and the smell afterwards was horrible:yuck:
Now dont forget this is the same car that was parked for 4yrs

no idea. thanks to the previous owner (and his crap fiat dealer) my 1.6 had been running for months with one injector spraying liquid fuel into the cylinder rather than a fine spray. as soon as the injector fault was fixed i could smell burning and saw the cat was lit up like a rear fog light, but its possible that the fuel in it was from running the car just before fixing it. maybe if you left it for a few hours/days it wouldnt be such a problem. in hindsight i think if i noticed the cat was burning before it got so hot it was glowing, i could have turned the engine off and saved it. just watch the cat, if it starts to glow switch the engine off for a few hours. the heat should get rid of the petrol soon enough.
Cool. Mines been layed up now for almost a fortnight. Really starting to despair of ever getting it fixed, with Christmas (and 14 nephews and nieces) the money's getting very thin on the ground.
At this point i can't even afford a tenner so buying whatever tool it is i need to get these things off is going to be impossible.
Got a really bad feeling that this is going to end up with a call to the scrap yard to pick the darned thing up.

if you have a grinder (or even a dremel with a cutting disc) you can chop the heads off the bolts. getting the upper manifold to come off would then be possible, allowing you to get a good grip on the remaining bits of the bolts. or if you want to do it the old fashioned way, get a big file out and prepare to get angry.
