One by one I keep knocking out the Jeeps problems, slowly but surely it's becomming more and more reliable for me.
When it's cold, even below zero, I can get it to start up and run just fine on the first start. I'll let it warm up and drive it to where I need to go, shut it down, even for as long as an hour, I come back, and all it'll do is crank over and WANT to start, but not actually start UNLESS, I floor the gas. As soon as I crank it with the gas floored, it'll start right up and run like normal.
It has 167,800 miles, and it has the I6 4.0L engine with the 4 Speed Automatic Transmission, and the old Renix Injection System.
All over really. Just old and rotten vacuum lines that are wore out. And the big leak was caused by lose intake manitold bolts. That caused a really high idle.
As I said before. I drive it every day. It's a totally random thing too. Sometimes it'll just start right back up, even after only being off for a couple minutes. Othertimes all it will do is crank over and not start until I floor the gas.
I have no check engine light, dispite the fact I think it's burned out.
What sensors should I look in to first and how hard are they to replace? I'm thinking about replacing the one on the transfer case just to be safe. I am not sure about the one in the dist.
