1047284 My 90' YJ in-6, 258 has the same problem. Sometimes I have to rev the engine while holding the starter moter until it finally fires up and holds. At other times the engine has to be completely cold for it to start. I've replaced plugs, wires, battery, ignition coil and cleaned...

1047500 Hey there, I've got a 90 YJ, but it also has a Carter carburetor w/o the stepper motor, too. I bought a carb rebuild kit and the worksheet manual says to set the choke thermostat cover to 1 - 2 index rich, so that's where I set it and it works fine for me. As far as setting the choke...

1047568 For those of you who are curious, I found out what that little ring gasket was for. It was for in between the choke housing and the body flange. It WAS in the digram, and I must've gone over it dozens of time. Well, anyways I can't replace that gasket because the screws that hold the...

1054628 If you're talking about the evaporative emissions canister, then it's there to control fuel pressure. It's charcoal filled and absorbs excessive fuel vapors that build within the fuel system. I'm very familiar with it because with my 90 YJ I kept smelling gas and couldn't figure out...

1054629 I have a 90 YJ and it had the same problem that you're describing. There are 2 things I can think of (by the by, my carb is non stepper-motorized): 1. Vacuum leak - especially with the hose that goes from the manifold to the vacuum advance on the distributor. (The hose is right there...

1054630 I'm almost sure it has to do with the SSI (solid state ignition system). I was a hair away from converting my carbed YJ to a TBI because I was so sure it was the carb. It took 200 to 300 turns of the key to get it going and what was weird was that it would sometimes only start when the...

1054670 Thanks Bounty Hunter for the info. I just came back from a local Jeep service center. They didn't have a 1990 service manual, but they did give me a printout of what transmission and transfer case assemblies that came factory installed by year. For me it's: YJ 1989-1990: AX15, 6...

1054690 I just noticed the build date for my YJ on my vehicle information summary that I obtained from my Jeep service center. It's 3/28/1990. If AX15s were installed after March 3, 1989 then I've no friggin' clue how I have a BA 5/10. It's over a year of installing AX15s! The hell?! Well...

1054768 Sorry this post is so long-winded: I have the non-stepper motorized Carter BBD 2bbl carb in my YJ. I believe that stepper motor is there to control the metering pins that adjust the fuel mixture according to the oygen sensor, which is controlled by the computer, but you've done the...

1055144 Make sure you have the right oil first (Mercon or Dexron II ATF) and enough of it. Drive around for about 15 minutes to warm up the oil so most of it will drain out. Looking from rear to front, on the driver's side of the t-case on the lower left side will be a drain plug. It's a...

1055154 I think I've found the answer to my question. My t-case is supposed to have a 23 spline input shaft. My t-case code # is 5300-8210. This site says t-cases with code # 5300-8210 has a 23 spline input gear. I hope that's the same as an input shaft.[addsig]

1055239 I've got a carbed YJ except it's a 90, but the problem you're describing I've been through before. If it's idling rough out of gear, or if it's wildly erratic while coming to a stop after some driving (at one moment it's idling at 2000 at one stop, and then it's on the verge of stalling...

1055274 I think JeepTech has the transmissions and transfer cases confused. The NP 207's had 21 splines when mated with a manual and 23 with an automatic. Jeeptech also refers to it as the output shaft. Isn't it the input? Shouldn't the output shaft have 10 splines, or have I got it the other...

1055281 I agree with Dingus. Even though I have a 90' YJ 4.2, I had the same problem you're describing. It would crank but never fire up and keep running. It would take 200-300 turns of the key to finally get some results. What was strange was sometimes it would only start on the first try when...

1055375 I'm glad you responded, RayOvac, because that helps my confusion with the input, output shaft thing. I do have the 231 t-case. I thought maybe someone on this webpage got things confused between the first two paragraphs, but I was the one that was. The webpage you gave me I've already...
