I doubt it. Have you ever done a proper ground refreshing or checked your sensor grounds per the TPS write-up?

You have a vacuum controlled valve in the heater hose near the bottle. You might want to watch the little lever while somebody turns the control from hot to cold. I guess to "backflush" you would run the garden hose IN the bottom hose, first, then go both ways. House pressure MIGHT be to high for the heater core, I just hold the hoses in my hand. Seemed mine took a day or two to completely burp. At first I didn't think it worked much, then it got better.

Is there a DIY anywhere on this? I have to drive to Indiana tonight and I will have to take the civic. And also, are all the ground wires black on each sensor? Because I will ground everything to the block if I have to. I need some help on this wiring for sure. That other tbs was helpful but cleaning it wasn't enough.

Well I'm selling this xj. If anyone wants her let me know. I'll hold off from posting it on Craigslist till Wednesday. Asking for $1250 obo here but posting it for $1500 on Craigslist. The engine, trans and 4x4 work great. Just needs the wiring to be redone and small leak from the oil pan. So if u r interested text me at 7084417997. I live south side of Chicago by oak lawn.

Not heading cross-country any time soon. Did you ever check your voltage? What are your issues now? Don't blame you if your fed up. I gave up on a Bonneville once when I was 18, over a stuck bolt!

Well I have decided to keep the jeep. The engine is still strong and these problems aren't as bad. But does anyone know where I can find a DIY to fix the heater?

Well today I will test and or replace my heater control valve, and change my fuel filter(s) (not sure how many I have) and check my fuel injectors. I have been having problems with her not wanting to start for a while ablation if she didn't have gas. So if anyone lives by oak lawn IL, feel free to stop by and help out lol

So yesterday when I was working on the jeep, I noticed the engine was shacking more then usual. And there was this abnormal noise coming from the belts I believe. I'm not sure y and it just started yesterday. I was going to do a back flush but after noticing that I stooped. What could that be?

I'm still at odds with this jeep. These problems are getting too frequent. I love my jeep but I really don't have the time to keep fixing problems. If anyone lives by chicago and wants a jeep I'd sell it. I want to find her a good home.
