So, after my Punto is now a new timing belt, water pump and cylinder head gasket I have only a poblem with it^^ And that always as soon as I turn the key the warning light of the single-pointing system runs out and after about 5sec again. Besides, the car runs at the cold start the first 5min about quite restlessly in the empty run, that stops as soon as the engine is warm. It consumes badly a lot of fuel (about 10l/100km), the exhaust gases also stink quite and the tailpipe from the exhaust (about 2 -3 months old) is very tired inside, looks almost like a diesel… Car now has 160,000km on it, can it be that the Lambda probe is? If so, can I still drive around with it if necessary, or what else can be broken? Thanks for your help wack
