I purchased a 98 Silverado 4x4 last week which has 177,000 km on it. It has the 5.7 and 4L60E tran.
Truck rides very nice and seems to have been taken well care of. I am the 3rd. owner.
Today, I drove 70km. into Calgary to get new tires installed. It ran fine the whole way into town. I had the cruise set at 120km/hr most of the way.
Coming back home I had the cruise set at 125km. and all was fine until I came to two short, but steep inclines. The truck started to buck/jitter while climbing these small hills. On the second one I attempted to accelerate, which only made the bucking worse. Once on level ground again, all was fine.
No CEL came on, so I have not bothered to check for codes as of yet.
As a side note, this past weekend the CEL did come on and when I pulled the codes they were P0141 and P0161, both 02 sensors behind the cat. I cleared those codes and all had been fine until today's trouble. But again, no codes were set today.
Anyone with some insight/ advise on what I can check or what may be causing this?
Appreciate it!
