360 Magnum '96 stalling rough idle and poor mileage
I have an '96 360 Magnum that's stalling occasionally, getting some really bad gas mileage (running very rich), and is idling quite rough, the revs also bounce sometimes between 600-1000rpm when in park.
Plugs have been changed and looks quite clean, here are the codes I'm getting (in order):
P0108 - Manifold Absolute Pressure/Barometric Pressure Sensor Circuit High Voltage
P0133 - O2 Sensor Circuit Slow Response Bank 1 Sensor 1
After a lot of reading I am thinking that it is probably my MAP sensor that needs replacing but I really don't know, anyone got any thoughts/advice for me?

I have considered the plenum but after a lot of monitoring I can report that it's not using a lot of oil, in fact it doesn't use oil at all and I'm not getting any pinging either. I'm pretty confident it isn't the plenum but I intend to do the magnet test if I get opportunity this weekend.

Need to pull the throttle body and check or signs of oil pooling.

Ok, thanks, look like I'm going to have a busy weekend! I am hoping it's nothing serious as the bottom was only rebuilt 15k ago (big end was on its way out). It has only done 83k now! Needless to say the previous owner has done a lot of work in the past (which is why I am hoping that all of the obvious stuff such as the plenum has already been done).
I'll give everything the once over and report back when I know more. Thanks for the advice.

Just another quick question if you guys don't mind....
The previous owner has put K&N rocker cover breather filters on in place of the standard part. They are due for replacing but first I want to know if there is any advantage to the breather filters or if the standard part is better, from what I have read there's arguments for both sides.
