CEL came on

HI everyone,

I have a 2000 Ford Ranger XLT auto trans 2WD. I recently purchased it with a butane system on it so I could switch between gas and butane. After some weeks the Check Engine Light came on. I was told it was because of the butane system on it so I had it removed. The CEL was still on so I took to a friend and had it scan.
The codes are as follows:
P1504-Intake Air Control circuit malfuntion
P1100-MAF sensor intermittent
P1101-MAF Sensor out of self test range
P1124-TP sensor out of self test range
P1127-Heated Oxygen Sensor heater not on during KOER Test
P1408-EGR flow out of self test range

If I change the MAF and O2 sensors will this solve the problem?
How many O2 sensors do our trucks have?(guy at the auto parts store said 4)
Do our trucks have a MAP sensor?

Any help would be really appreciated
Thanks in advance!!!
