Hi Hab n Problem with my Sierra Hab already written that he is sometimes a bit jerking. thought it might be at the open Luffi War only of short duration and then went away again and again. Jetz no more. sounds like n trecker, in the front he sounds actually so normal up to a clacking what sounds like too little oil though there is enough in it. Runs like that and sounds like he’s running on 3 pots, because pulls also no more and even nix. What could that be? I thought of spark plugs, maybe n ignition cable or the distributor or the distributor cap. Must look tomorrow what it can be What’s funny, however, is that it was always quite short before before and jetz from one moment to the other in the ass. Last weekend he drove still without any problem. Hey evening I drove down from the property and then he was still normal, goal made again and swollen was the trecker on the way. At approx. 2000 rp the car sounds quite normal and half way to be good. If you want to take it from me. If you really want to take it from me.
