2004 Lariat*Ford*F-150*5.4 Triton. Whenever I slow down, stop, or turn my truck will read low oil pressure, then all my gauges drops and it stalls out. I've taken it to my mechanic twice now. And twice he's replaced two sensors for $260/ each. Today I took it to Wal-Mart for an oil change and they said its probably why my check engine light is on code, T19. I've had that light on for 4 years now and this stalling out problem starts 3 months ago. So far its had regular oil changes, new air filter, two new sensors and im scraping money to throw at it. Hitting snow banks, other vehicles, and tree's... need to find the real problem before I go broke or worst kill someone in an accident. Pretty please can someone tells what's going on here.

The gauges drop and the oil light comes on because the engine is stalling....

Go get the codes read. The computer is trying to tell you something and it may be important.....
