multiple MIL codes and car shaking/sputtering
 

Backstory: 1999 3.8 vert with 230k miles oil changed every 5k since I've owned it the only mod is a CAI. For the last couple of months it has had a bit of a hiccup when the engine is under heavy load like going up a steep incline(feels like a cross between a backfire and the transmission trying to slip). A month or so ago it popped a MIL for the rear driver side Oxygen sensor.

Last week I ran a third of a can of Seafoam through the vacuum line, but it did not help the hesitation. The car has been running the same until today. This morning I put in a new O2 sensor and cleared the codes. Car ran fine for about 10 mile then started shake and vibrate like crazy. Right as I pull into the driveway the MIL comes on. I run the codes and it is popping all 4 Oxygen sensors as well as a P0443 Evap circuit fault.

Has anyone run into this before? I checked the gas cap and the main vacuum lines and they all seem fine. I'm at a loss so any and all help is appreciated.

Well, I did some digging on other forums and found out that it was the dreaded yet cheap to fix blown fuse #8. So I replaced the 20 amp #8 engine control fuse and everything is fine. Wooohooooo less than a $1 fix
