MikeT Posted May 14, 2020 Share Posted May 14, 2020 Hello all. First post. Bought my Audi 90 about 12 years ago and a very intermittent (almost non-existent) fault has become full time. Initially a very slight and very infrequent misfire has morphed into not running at all on cylinder 3. I have done all the obvious things such as fitting new plugs, leads and distributor cap and I have ruled out (by substitution) the fuel injector on cylinder 3 and the ECU. Compression is good on all cylinders and with plug 3 out of the block it still sparks well, but is completely black (dry, not oily). Is the fault likely to be in the distributor body itself and where can I get the part number? (not easily visible in situ). The engine is 2309cc, and the car was first registered on the 1st Jan 1992 (J5 AUB). Thanks in anticipation. Quote Link to comment Share on other sites More sharing options...
