Have an 81, all stock with factory smog. No other mods have been made. To date I have done the following (all OEM parts):
Fast forward.....Last week it was not as bad, and when coming to a stop, engine idle would waver and stumble - and eventually stall. As of yesterday, engine now stalls with coke in - which is now worse than last week. Give it gas and it pulls out of stall and I get belt squeal pretty badly...this is always at low RPMs...I do not get belt squeal when driving around town. After giving it gas and letting it settle to normal idle...stalls.
Fuel sight glass shows fuel dead center - even when it stalls.
By the "Whatever you changed - star there" Law, The only changes I did Last week - I was washing off my transfer box with degreaser and with water hose....sprayed around that area, but nowhere near engine bay.
I just need to know where to start to figure out if this is carb adjustment or something electrical. Clearly this can be a vac leak with a fully smogged FJ - I will check vac today, but as of a month ago, vac was solid/steady around 17-19 with no needle bouncing at idle.
Thanks for any help!
