So I'll drive my 4.3 non vortec for a bit then shut it off for line 10 min then I'll start back up and it bogs down. The oil gauge goes up and down over and over and it won't quit bogging down unless I...

Replace the fuel injector system. When you shut it off, the fuel continues to dump in the cylinders. This is the reason you have to open the throttle and rev the engine up. Getting rid of excess fuel.

I have noticed that if you keep the 'A' pedal down it simply revs beyond 3K and doesn't actually accelerate. The trick is to ease off the 'A' pedal, see the rev coming down and then accelerate again. This will save fuel also. You will see it cruising at around 45 miles just above .5K rev when you do this.

Flashing light on my dash of a engine

hi patricia
FIAT engine light flashing means the ECU needs adaptation,
you can do it yourself just follow this procedure.
( remember not to accelerate unles is stated) start the engine
let it to warm and wait for the cooling fan to come ON then OFF 3 times, like ON,OFF,ON,OFF,ON,OFF. After the fan cuts off the third time accelerate fully down let the engine rev up to 4000 only then leave the accelerator let the engine goes down back to idle, do this 3 times.the engine light should go away.
good luck

Nissan pathfinder cutting out

I read somewhere that the problem was related to the sensor in the brake pedal, when it goes bad it confuses the computer, no input to indicate that the brake was applied, so it basically goes into limp mode, press the accelerator all the way to the floor and you get only gradual acceleration.
