I have done so much to this truck I am just about to throw in the towel. If some of you aren't aware of my build thread this is what I have so far. 1987 renix comanche, 4.0L AW-4 Renix wire harness, computer and tcu from 90 Cherokee '95 block '99 intake Billet 63mm throttle body with Hesco adapter for renix sensors Hesco adjustable fuel pressure regulator Wideband O2 New sensors I've installed TPS IAC O2 Now onto the problem(s) The truck idles very high 1500-2100rpm when in park and the torque converter doesn't lock up. At 45-50mph the tach is over 2K. I have went through the wire harness and cut out the sensor crimp and resoldered the connectors. I have upgraded the battery, body and block grounds. Everything was cleaned and dielectric grease was put on the connectors. Now I have tried to adjust the TPS a number of times in the past 8 months I have had this problem. I cannot get the required voltage without the throttle plate stop screw adjusted so the throttle plate is cracked open. This was today's activity. So it used to idle about 1500 rpm and now it idles at 2100!!! I pulled the "new" iac and the plunger came apart in pieces, it unscrewed and the spring and rubber piece was all in pieces. I reinstalled my old one and no change. I unplugged my MAP when the truck was running and it died. I don't know if that's right or not. I have not tested the MAP. So I have no where to go, I have been working on automobiles for 20 years and this is the worst one I have ever worked on. I can't seem to get it right and I really want to drive it to break in the motor. So if Cruiser would be kind to work with me I would love it!! I really need someone to come up to trouble shoot the problems with me because I don't have the patience to tinker with it blindly all summer. Please help me get this right.

I bought an optima yellow top last year or two years ago and I haven't been impressed. It dies quickly and it doesn't like to be recharged. I have the Craftsman digital AGM charger and it won't charhe unless I put it on 15 amps. I would like to call advance to see if I can get my money back. Thoughts?

Didn't change anything, I guess I'll have to try buying another oil pressure sending unit and test the voltage against the gauges again. Anyone else have this scenario before?

I always enjoy looking at your thread, the blue is such a nice color. The background is spectacular!! I drool at those pictures since I live in flatland Michigan. One can only stare at water for so long.

I will do that, I'll let you know by Tuesday or Wednesday thanks!

My gauges are off and I was wondering if anyone has any tips of what could be the problem. "87 Comanche 4.0L "well 4.7 actually" auto 4x4 My oil pressure gauge is about 20psi low My volts is low, around 2V below what is measured at the battery I don't know if the fuel is low because when the light comes on I fill it up and it goes from empty to full without problem Tach works fine but I have no way to test against the gauge. Spedometer seems accurate, but I haven't used the GPS to verify "probably should" What could cause the first two to be much lower than normal? The oil pressure sender is original but I can't see why it would go bad. I don't know what picks up the voltage.

I have some leftover parts I just can't seem to determine if I want to sell. 40k mile '87 renix 4.0L 40k mile BA10/5 2wd 5 speed Complete AW4 with 231J from another Cherokee 87ish I also have a 23 spline 231 that I would like to use instead of the 21 spline AW4/242 combo from a '90 currently. I would need a newer AW4 to use it though. I am stuck in a parts war since my stroker motor is in. What should I do?

Yeah they suck I will agree 100%, and I have removed mine (242 as well) AND the aw-4 AND the engine quite a few times. Maybe if someone was smart they would have made a seperate crossmember to hold the trans in place. I have better luck removing the trans with the transfer case and then seperating them.

Sweet truck!

Bad @$$

I haven't had much problems except it is VERY SLOW! I click on the img box about 10 times until it highlights the box yellow and copies the link code. The stupid ads slow the website down considerably. I would love to use Picasa, but as far as I know I can't get the img codes. I have searched online and my picasa doesn't work like what's online. Picasa doesn't have any ads (yet) but it won't work for me so far.

My wife spent 7 hours in paint shop and made a shirt for me. http://www.zazzle.com/comanche_3_shirts-235184819111923814 The picture is bigger on the shirt that I have.

I took a new Cherokee for a drive last week. I was very impressed. I chose one with the baby Pentastar V6, they didn't have a trailhawk with the V6 on the lot. The stereo system was worse than poor, if you are considering one get the upgraded audio. It handled excellent in the snow and slush, the new abs brakes and all the electronics really doing their thing nicely. The rear seat has a TON more room than our old XJ's but the rear hatch cargo has gone down quite a bit since the rear end is so rounded. I did notice that the spare tire well is HUGE!!! I would love to put a nice 15" sub in there!!! I have a XJ, a WK and an MJ, to this Jeeper I approve.

Good to hear!

Hard braking to the left could mean you have a bad right front caliper or colapsed brake hose.

I really like that bed and the nice letters on the tailgate.

I appreciate all the help, thank you!

Man I love those wheels!!!!! What kind are they? MJ bolt pattern?

That sounds encouraging, I too have fell into a rut since my Jeep hasn't treated me well since the whole motor debacle. It's good to hear you are doing well and came to your senses, I just hope a similar situation happens with my deflated feelings about my Comanche.

The stickers are grey, the same ones that are in my profile picture.

I have a set of the SporTruck stickers new in box that I ordered from Jeep sticker. If you want it PM me and I can sell it to you. I decided not to put mine back on.

I have the Renix system, so the Hesco adjustable fuel pressure regulator doesn't use vacuum anymore so you just set the fuel pressure and leave it. That doesn't really make sense to me since the engine would need more fuel when revs/load increases. It just can't seem to be adjusted purely by injector pulse width. I hope I don't have the lines on backwards, supply to return or I'm missing something? As for the check valve that's a great idea, I'll check out that link thanks.

done

Ya know I realized that the track bar and mounting points need to be REALLY strong when lifting with that type of long arm kit. I'm sure it will ride a lot nicer with that setup.
