Audi A4 missfire
Hi everyone out there,
Ive got a problem with the car, cel came on, pulled the codes and none came up but when i pulled one of the ignition leads out from the spark plug [plug 2]the car was still ticking over the same as before but when i pulled plug 1 the engine sound changed as if running on three cylinders as it should but both plugs were giving out a spark when i placed them near metal,I found this very strange, however as i pulled on the throttle body to rev it up the spark didn't seem brighter or larger just faster, i wonder can one poor lead actually make the car hard to start, but still allow it to tick over rough 800-1000 but when you rev it up make it missfire, just to add I did spay some wd40 on the leads and it started better but still missfired 5 mins later any ideas please
