Seems to want to back fire a lot through the exhaust manifold. It idles nice and strong after a full turn to the right ....that’s all I did no disconnecting battery no hard reset

After I cranked that idle screw to the right . I gave it some gas lightly here and there to keep it from stalling. I then it got real poppy sounding on my exhaust manifold I’m pointing to here. It actually sounded super bad ass and then I walked over to the muffler and had a strong popping sputtering sound.. but when I shut it off I heard a a lot of swishing around of fluids And bubbling of fluidsaround my radiater possibly that was unexpected how I’m guessing it got real hot it sounded like it had 800 horse power lol

Put on a new map sensor 70 bucks . I’m running this truck at a higher idle turned screw to the right ( I didn’t bother with an iac reset because wherever I turn that idle too it still keeps position when vehicle shut off)now seems to help I have to gas the idle a bit a few times to get it to smooth out and sounds really good when in gear.

Truck starts and runs good now except that I shoot oil out of the dipstick and coolant bubbles and fills up the reservoir. The coolant drains back into the radiator when the truck shuts off

That’s not good. Sounds like a possible head gasket issue

I once had a plugged up PCV valve cause occasional smoking out of the dipstick. Oil shooting out of one though, is something I've not seen, lol.

A weak radiator cap will have trouble retaining proper system pressure, which can make the coolant bubble into the overflow when it shouldn't.

The first thing I would do is drain some coolant to lower the level and then perform a block test.

You can get the block test kit with a squeeze bulb, or with a vacuum line that hooks to an engine vacuum source.

If the fluid stays blue in color after running the engine for a minute or two, it's very likely that there's not a combustion leak into the cooling system. If the fluid turns yellow, that's when you are looking at doing head gaskets or more.

Took it to the mechanic my timing was too advanced, loose exhaust manifold bolt loose. The rubber on my radiator cap was gone this caused my coolant to back up in my reservoir 280$ covid price not too bad
