I'm assuming I'm burning rich, my question is what do I need to check?
Ok I have an 89 renix with a 4.0 and 255k miles on it so no OBD, i average 12mpg in town driving easy in 3rd with 31" tires and stock 3.55's. last night I changed the coil/cap/rotor, changed the plugs 2 months ago and taylor wires aRe on order, also changed O2 sensor but didnt help. Its got a new muffler so stocks off, I've tried Z-max oil treatment but it didnt do much for me lol.
Reason for the coil/cap/rotor bug was it got cold recently and my jeep would take forever to start, just cranked and cranked, I thought it was fuel but my pressure was low but good,cranking was near 38-40 but at idle it was about 30-32 lbs, once it started it was fine, since the change it fires right up, now I'd like to fix my to rich issue... What else can I look at? All my vac lines look old and brittle, but don't think there is any leaks. It's not a carbed Chevy 350 so I'm kind of lost, any help would be great.
