Guys can anyone help... i have a jeep cherokee with a 2.1 diesel engine (it's a different engine, a renault 4x4 engine ). The problem is that when im going uphill and rev it up it starts running away(run away diesel), however if i drive through the city (streight road , no hills) the jeep drives fine, when it starts running away up hill the engine oil starts to come out the exhaust and there is a lot of smoke but as i mentioned when im driving streight( no hills) it does just fine and it doesn't smoke a lot. Does anyone have any suggestions on how to fix it plz help...

I have about 21/2 to 3 inches of play that has developed in the gearbox. Is this adjustable or do I need to just replace it. Going down the road above 60 mph the front end will vibrate violently and I must come almost to a complete stop for it to quit.
I bought a 92' straight six 4.0 Jeep Cherokee. I thought I was getting a good deal but may have ended up with a headache. After a month of driving it, my thermostate gasget cracked causing me to lose coolant. I replaced the gasget, theromastate, and added more coolant. Later started having heating problems at the start of summer. I added water in to the cooling system thinking this would help. Than took out the thermostate to check for problems. I was told I could leave it out as long as the weather isn't cold. And the past few weeks when I get off it is cool but not cold. Now I have a chirping noise underneath my hood and I am figuring it is coming from my serpentian belt. But don't know if it is a pully, belt, pump or what acting up. Can anyone help?
