89 yj smoking... engine swap or ?
Hey all I'm a newbie to this forum and a Jeep newbie in general.
So anyhow I bought my first Jeep a few months ago now and unfortunately didn't have any knowledge of them. After buying a buddy in Colorado informed me, 89 is headache and tried to guide me to sell and get something else. Well I'm not able to do it, so I gotta work through it.
So lately she's been smoking intermitently, seems like sometimes she does upon start up a bit and others upon stopping (may be just unnoticeable in movement). Being Carburated she's always smelled rich, but now is more apparent. One of my buddies suggestions was an engine swap to Fuel Injected 4.0L right from the start, so I've been looking but upon doing so am seeing I'll need a whole lot more than just the engine... computer, wiring harness, fuel pump and lines etc. etc. etc.
I drive her and though I plan to do more offroad, she needs to be street legal.
Being in CA that means 'Smog checks' every 2 years.
I'd be totally happy keeping the stock 4.2L (tilll maybe a later date, or forever), but ABSOLUTELY have to solve the smoking issue. I recently got a notice that someone reported it, so now 'the Man' is watching me.
HELP!!! I found some links on here (OMG there are millions it seems) on things to look at, and have gone through some of the checks... PCV seems good (as it rattles as suggested), stepper motor, computer and O2 sensor working (not sure if that means they are working 'correctly', but the carble needles are apparently adjusting mix as they are in motion, so ????
Anyone have more, suggestions, opinions etc?
