Already have a gremlin...
Hey guys, I have a little issue with the truck and I'm not even sure where to start looking. I've been driving about 150 miles round trip for the past couple weeks, and a couple times it would get jolty but I could never tell if it was the truck or if it was the road. It cleared up in 5-10 seconds so I always assumed the road. Today it was DEFINITELY the truck. When I say jolty, it's like a gas engine that's running out of gas right before it dies. Today it did this for about 10 minutes then it cleared up for a few seconds and then did it again.
I decided to get off the freeway and call a tow truck because last time this happened (a month ago), I blew up my 6.7 lol. I get off the freeway, truck is idling like crap, light turns green so I start to go and now the truck is running like normal. Has absolutely no issues so I decided to just drive it home and in that half hour there was no issue.
The only thing I know it needs is a battery but would that cause this issue? Looking at my SCT X4, my coolant temp always stayed between 195-200 and my oil is 5-7* above that. EGT's maintained below 800, trans temp was in the 160's, FICM voltage was 48.48.5, fuel pressure was and usually is between 59 and 61, and battery voltage bounces between 13 and 13.5.
I'm getting new batteries tomorrow just because it needs them (1 is good, the other says it needs charging but we charged it and the truck will still have a hard time starting if I leave a door open for 5 mins). Can I unplug both my batteries for a long period of time (about a day) without anything happening, or should I put the stock tune on and expect to have to re put in my radio stations?
