cherokee overheated, now runs rough...
I was driving down the highway yesterday and I could smell something burning, turns out it was my engine, The temp gauge didnt read it was overheating but clearly it was. I ended up pulling over when I realized the jeep had hardly any power and I was hearing a ticking sound that got quite loud. There was coolant leaking everywhere under the jeep. So i got it towed to my parents house and looked at it. Turns out a frost plug had a small hole due to corrosion so all the water in the block had drained out. I put a rubber replacement frost plug in it and topped up the coolant. So now it runs cool and all that is ok, but the jeep runs very rough, especially at low idle and it backfires when accelerating at low rpms and pulsating when not under much loud. It also barely idles. It isnt blowing any smoke and there is no water in the oil. Tommorow I'm gonna do a compression test and see how that is. Any ideas on what may be broken??? it runs strong at the higher rpms just not good at low rpms.
any help is greatly appreciated!
