Hello, does the check engine light come on or the overdrive light?

Customer: replied 2 years ago.
engine light used to come on but changed mass air sensor and it went out
codes show too rich fuel mixture before
no overdrive light comes on at all
Customer: replied 2 years ago.
also started truck up again and disconnected throttle position sensor
while running
depressed accelorator and same result was sputtering and revs max out at 3000
reconnected again the tps and no difference
was wondering why with no history of engine trouble like this before this truck just started acting up
Customer: replied 2 years ago.

your trouble shooting suggestions would be very useful please
