Well last night I went to remote start engine after a wrestling meet, 40 degrees outside, It did not work, I put the key in and it started; but ran poorly, low power light came on in instrument panel, car was barely running, Check engine light was on. Also the light for spinning tires came on. Well I made it home, tansmission shift points seemed changed, cruise did not work, low power all the way home. Check engine light stayed on as well as the squigle tire light.
When home I turn car off and waited 5 minuets. Car started with key, Check engine light was on all, other lights normal, all else seemed normal, car ran fine, transmission shifted OK, cruise worked. This morning went to start car with remote, it did not work, locked car seemed to operator normal, push remote start on fob and lights can on and stayed on with no start of car engaged. Put key in ignition and car started. Ran as normal with Check Engine light on. About 20,000 miles.
I was planning to make a 2000 mile trip starting at 6 am tomorrow morning. Do I have to take it a dealer first. I would have no problem driving my 1966 chevelle as I know how to fix any problems with that engine; but this 2017 silverado 5.3 is a puzzle to me. Please help if you can.
