I have a 2003 silverado that has been having rough idling issues. The truck doesn't idle rough everyday,but when it does the voltage fluxuates between 10-14 volts. Before this started happening it stayed at a steady 14 volts. Now the voltage is dropping and the rpm's are dropping to around 200-300 rpms then some times it will die in motion. I have replaced the alternator and had the battery tested they are good. There was low fuel pressure so I replaced the pump,still nothing is helping. . Read more...
Noticed on my 2003 chevy silverado that when I put the key in the accessory position that I can slip the gear shaft into drive, reverse, whatever, without depressing the brake pedal. Also have noticed this on multiple 2006-2007 chevy express vans. When the key is in the start position or engine is started that the brake needs to be depressed to place into gear.
