Im a freshly owner of a 16v ABF mk3. Been restoring it for the last year. Engine parts has been fully refreshed such as leads, dizzy, rotor arm, spark plugs, timing belt, oils and filters. But i notice the engine not running smooth, idle at 920rpm on VagCom, sometimes it revs up to 1500~2000rpm and also a LOSS of POWER. (owned a 1.9tdi110 and i think it was very close to this) Checked for vac leaks, and replaced all vac pipes to be sure. Cleaned also the isv. Checked relays, and seems ok to me. Any suggestions?
