90 YJ??

[Jeep_Babe98TJ]

I was looking at this 90' YJ, and I told a friend about it and he told me not to do it because it was carburated.... and not fuel injected. He said 91' was when they started making the fuel injected. But I really like the jeep... Is carburated bad?

[H8 PVMT]

Only the I6 was Carb'd in the '91, if it is a 4 cyl then it's FI. Carburated isn't bad but in my experience you will run into more problems with a carburator than you will with a FI system.

Nothing wrong with a carb, but I like fuel injection so much better. I have a 92 4.0L fuel injected and I have never had trouble starting in cold weather. It runs smooth all the time. Plus the FI engines have gobs more power than the carb'd engines. Granted, the carb'd engine is very torquey.

If oyu like it and it is in good shape go for it. The carb is an easy fix. Mine runs fine after having the carb rebuilt and the tubes opened up some.
Or for a couple hundred dollars you can get a aftermarket one. I love my 90.

I drove a carb'ed 90YJ for about 5 years, before converting to FI. It isn't that bad if you can adjust to the problems you will have.

When the carburater works, it does well. When it starts to have problems, they are a pain. The carb was good until a ton of vacuum lines for emmisions controls were added.

its a 6 cyl. , well this friend made it sound like to stay away from it... he said that it will cut out doing hills.... how good do jeeps tow stuff, and how would this one do towing... I have a 98 as of now and its lifted with 33's, but its only a 4cyl. and it has 4:10's gears... i havent even tried to pull anything with it. this YJ has 95k miles on it..... and I can get it for 4000,
here's the pic..... its the black one.... http://community.webshots.com/user/jeepbabetj

The 6 definatly has more power than the 4.

Towing is another matter. While the 6 can tow more the the 4, it's all a matter of wheelbase. Wranglers are short vehicles and are not designed to tow large things. You can get away with a couple of Jetskis, motorcycle carrier, small sailboat or something similar. Anything bigger, you have to be real careful.

The carb has some problems on long steep hills but not too much.

I would keep what you have. Geared right, a 4 banger can do some amazing things.

[Jeep_Babe98TJ]

I wish I could keep the 4cyl. I love that thing.... and it can do some amazing things :) But just bought a house and half to cut out some bills.... and unfortunately it has too go..... so I'm looking for a older cheaper jeep.:naw:

[Sequel]

I had a '90 several years back and now I have a '92 and I think the fuel injection makes a big difference. Carbs have problems on hills and they also don't appear to have the same power at highway speeds. I think the FI makes the engine compartment cleaner thus easier to work on, I think FI is less prone to problems.

I'd try to find a '91 or later FI 6 if possible, but if you have your heart set on the '90 then go for it.

Mine was a I6 4.2. I put 100,000 on it and replaced the carb once. (it backfired through the carb a few times and eventually bent the choke shaft slightly over time). So it started running rich. Was an easy swap and there are aftermarket carbs that can improve perf as well.
It can flood out if you stall on various types of inclines but that is a driver experience level issue. It never stranded me or anything bad like that. I did mostly 4lo crawling at idle speeds and going a consistent steady speed for that type of driving I had no problem. An older jeep like that can have things like rear CS main seal leaks, Clutch slave/throwout unit wear. Also make sure its not a Puegeot Tranny like mine was. Rebuilt ones cannot be found and having them rebuilt is expensive. Mine needed a reverse, and first gear rebuild as well as mainshaft and bearings $3000. 90 YJ's may or may not have that type 5 spd. (left overs from AMC/Jeep/Renault era)

I think it was a bit more Zippy than my Rubicon due to being 4.2L. Those years also only offered like 3.07 or maybe 3.55 gears. Unlike the TJs which moved up to 3.73 with the D44 rear option. So running large tires will dog you down a bit if it has 3.07's ( ran 31x10.50 )

the I-6 was injected in '91...

I have a 90, 4.2 carb, just don't turn it off on a hill, heel of a time starting it again (of course mine is messed up, saving for that weber again)

i towed with it the fist time yesterday, a bike on a trailer, maybe 1200 lbs, like it wasn't even there:yup:

[catts258]

$ 4000 sounds like a fair price, especially considering the low miles and what appears to be overall good condition.

DONT GET THE CARB

[Ron90YJ]

OK let me add this also... Everyone is against the carb it seems but what you have to think about is what you want, and what you can afford. Carb replacement options are 1) Webber 2) MC2100 (did that one) 3) I am sure there are others.

The MC2100 is less expensive than a Webber and in my opinion I have heard of too many guys having tuning problems with a webber. I really liked it and it got rid of alot of the vacume hoses under the hood.

If you decide to go FI you can take a 4.0 head and assoicated parts and put it on your 258 and you would be amazed at the power difference.

Is there any doubt in my mind that FI is better NOPE but I started with a 90 with a carb and now I have a 90 with a 2000 FI TJ Engine. I am much happier. Dont let the carb be the ONLY reason you don't buy the jeep.

[sstaurus]

The 90 will not have the puegot so don't worry about that. Halfway through '89 the tranny was switched to the AX15 on the 6cyls.

If you like tweaking and/or are willing to learn how to mess with a carb then go fer it!

[YJ4LIFE]

people act like its the end of the world. Don't like it? TAKE IT OUT. 4 bolts and a throttle cable. big deal.

With my Weber, I use zero vacuum lines. No emission ****, no nothing. I can fix my carb with a flat head and philips screwdriver. Can you fix your FI with those two simple tools? I know I couldn't on the '94. Having the stock jack holder out saves you a TON of workspace, highly recommend it. Look at the spark plug location, the engine bay over all.....

STEEP climbs and MPG....FI
Ease of workmanship and simplicity....carb.

[YJYankee]

I agree with everyone else... If you really want it, get it. I own a 90 YJ with the Weber Carb. I haven't had any problems with stalling & I've been on some pretty decent inclines/declines. Like someone else stated, with the Weber, your eliminating all of that mess otherwise known as vacuum lines... It improved my throttle response & gas mileage...:clapping:

Go with it!
