Well, this is 1998 beetle 2.0 stick shift, I took to get codes read, had all 4 missfire, po440,po116,po300, nd po301-302-303-304. since I put new plugs[one was broke others BAD] ,new wires and coil pack, when I changed the OLD fuel filter it rattled bad[came apart inside] and dumped it and ALOT black crap came out? SO, new filter and will try to start then nothing, I took fuel line off and sprayed all over good preasure, it will run on startting fluid, my thought [tell me if I am wroung] is since fuel filter came apart is there a good chance alot crap got to the injecters? and if so can I take them out check or clean?? And is there anything else I am over looking with all this??
