when I started my truck today it was idling low and it was sputtering. it was cold and my truck was plugged in when I started it. when I would come to a stop and then go again it would take awhile for it to move and the I stopped again it stalled. when I started it again I noticed that my oil gauge was showing low oil pressure but no warnings were coming on, oil pressure reading was half way between 0-275. I noticed when I would press the gas peddle and idle up my oil pressure would go up. it is over due for a oil change.
