Bear with me oh knowledgeable Pelicanites please. I'm not much of a mechanic but still like doing what I can. Here's the symptoms.
1 Car was overfilled with oil but has been drained to appropriate level.
2 Starts very well and goes through a solid 5+ min warm up cycle
3 I've looked over for vac leaks and nothing glaringly obvious
4 No ox sensor with backdated exhaust
5 Decel valve plugged
After warm up engine hunts for idle and will not run without a bit of nursing along. If I remove the oil fill there is a change for the positive regarding idle. Idle will then not hunt and even with rev will return to a solid approx 1000 idle.
Car does seem to be running fairly rich ( from smell only no co/ox/fuel equip). However car does perform on the road quite well with no stumble etc while going through gears... just stumbles and hunts when it returns to idle.
Thanks again for your help... I'm learning but the curve is rather large
