Hello , am new here and have a question there. I bought myself last week an Omega B 2,0 16V year 1998, which has only run 83000 Km and very well maintained ( pensioner vehicle ). If I drive and the gas hold it more times less, but is quite annoying. Maybe someone has an idea what this could be: at the cold start morning makes probably the exhaust or the flex or trouser tube a little noise, but only if it is cold, if it can probably be because !!!!!!!! Greetings e Michael PS , I am grateful about every tip
