I'm swaping a 1990 5.0 into my wrangler and i'm curious about the vacuum and smog equipment. Mostly the valves on the passenger side fender well and how I can plug them. If I remove everythign but the EGR valve will the computer not throw a code?

Looking for some assisntance thanks

im not 100%.. but i thought i would chime in since i have a 90 5.0, and am a ex owner of a 89 jy wrangler which i was gonna put a 5.0 in.. i miss the jeep and am going to get another and drop a 5.0, so id like to know how this goes for you, what did you get the motor mounts from? any other info on the swap???

and by the way i think the computer will just put the check engine light on.. no biggy.

I'll have to have my driveshaftes re-sleved and air-con hoses made and so on, I live in SW Florida so it is hot down here most of the year.

The rearend has to go, I'm swapping in an 8.8 out of an explorer with disc's and 31 splin shafts.

I'm running 4.10's right now with 33" BFG Muds but the future holds some 35" claws.

That is about it,

about the vacuum, when the computer turns the light on will it put it in limp mode?????????? I thought when it threw a code it would throw it in limp mode?

Thanks

no it shouldnt throw it in "limp" mode, im pretty sure anyways..im not an expert on this but no one else is trying to help you. ill try to ask some guys and find out better details for you, but i think this is gonna kick ***..post some pictures for sure.

so you had a 4cyl wrangler right? the 4:10s gears were factors i beleive right. maybe try for a rear from a ranger 4wd. it would have 31 splines, disks, posi rear and 3:73 gears, pretty much a perfect off road rear.

if youre going to stay EFI with the swap its going to be very very tricky to get the CEL to stay out. this doesnt however mean that the computer will go into limp mode. if it were me, i would swap to carb, and be done with it, much more reliable as a swap. you might be able to find someone that makes the HO EFI harness for this conversion, and i would start with summit and jegs. as for the rear end, i would go with the ranger also, but im never seen one with rear disc brakes???

I have all my emissions crap behind the pass strut tower unplugged and taken out and there is no check engine light. I also took off my egr and had to get one of those delete things from ebay.

if you get an egr delete tape it on the plug.
for a whild I had the check engine light come on sometimes, and right away I knew it was the plug.
