Hello! I drive an Audi 80 year of construction 94, 2,0E 117 hp. I have the following problem: My car is generally bad, if for example on the federal road sometimes really acceleration then it always pulls so piece-white, so well then again about 2000 revolutions bad then comes again a thrust and so on. So just never in a flow. So much to that. But that is not my biggest problem. Now it just does not start to pull at all during the ride. The speeds fall n into the basement and if I continued to give gas, it would probably go out too. (If I went off the gas too late he would also get some kind of misignition, so he SHOWS something). It feels like the exhaust was completely clogged and the exhaust gases could not be removed anymore. Then I push the clutch, let it out again and sometimes it works that after repeated this procedure I can go back to normal as if nothing had happened. The mistake has no particular pattern as it occurs. No matter what weather the car is cold or warm. Then it’s sometimes a week at a time when it just spins around and then again a week nothing. I have no idea what that can be and would really be very happy if one of you could tell me tips or maybe even the solution.
