HELP! I have a 2000 dodge ram that has been sitting for a couple months. The weather in the last few days has gone from60s and 70s to 20s and 30s and when I drove it today the oil pressure was going up, up, up! I didn't want to cause additional problems so I took it back home instead of to the mountains
It has a little over 100,000 miles. Before leaving the house i checked under the hood to make sure all looked well. Also checked amount of oil and antifreeze. Any suggestions?
