2004 Silverado problem, high rpm on park.?
We have a 2004 Silverado that we rarely use and today we decided to turn it on and it wouldn't start since we had it sitting there for a few weeks. We charged the battery up and it turned on just fine except the check engine light turned on and it said reduced engine power. Also it was rpming at about 2000 on park but once put it in reverse the rpms would drop. What could be the problem?

With the age of the motor vehicle it may desire to be the two. in case you have a 24v motor its additionally hassle-free to make certain the rubber line that is going to the %valve injury, yet that could desire to make the verify engine mild come on
