Need help. I have a Jeep that will randomly stall at corners (usually at the worst times). There is no sign that it is getting ready to stall. When it does it takes any where from 20min - 12 hours to start again. It will try to crank but will not fully turn over (Start). I have also noticed that the oil guage bounces all over the place. When first starting out it will bounce any where from comp. off the guage past 60 then hit 30 then maybe back up to 50-60 etc. all within a about a half of block until apr. 5 miles or so.

Any thoughts????

 

sounds like you have a bad pressure sensor. on the stalling part, since you will randomly get a bad crank, and stall especially on corners...then i would say you have a bad ground. first take off the battery terminals and clean them really good. then follow the negative cable all the way back to the block and ensure the stud and the nut are in the block tight!
