I have a 98 Dodge RAM 1500 4WD pickup truck and when it is going up hills and accelerating past 50 MPH it likes to vibrate and buck all over the place. At one point it just decided to stop running and wouldn't start anymore. I took it to a shop and they replaced the distributor and the cap and it runs now but it still does this as I couldn't afford to get a new o2 sensor and the wires that go to the o2 sensor that are on there are too short to solder back together as they were cut when the catalytic converter was removed and replaced. Also there is some type of oil leak causing one or 2 of the spark plugs to get fouled up fairly badly and I think I am going to get some antifoulers to temporarily fix that issue. What I am wondering is that if running without an o2 sensor can cause the cylinder walls to get torn up really bad from what I heard. If so then will getting a new o2 sensor fix the issue and it run fine even if they walls have gotten torn up very badly or not.
