Ok so On my 1989 325i I did some work to it and did my intake manifold wrinkle black, replaced manifold gasket and tb gasket, had my injectors tested and cleaned and caps and O rings replaced all tested to be working perfectly fine. did my timing belt and water pump as well but I don't think it would have anything to do with my symptoms. lastly I replaced the fuel lines from the return and feed lines to the rail and the one small line to the evap canister thing. anyway I had the car idling and it sounds like its not very happy I have my suspicions on bad tps cuz there was no continuity in it after I had opened it and cleaned it. lastly I am sometimes getting the lambda 1 code (1222 Motronic code) and some more smoke/bad smell coming out of the exhaust so my thoughts are its running rich. will a bad tps be the cause to all of this? I think it could be because the engine is trying to tell itself how much fuel to inject but the tps is not sending that signal. car drives fantastic other than this idle patchiness and blipping the throttle is not an immediate response.
thanks.
thanks.
