03 LR Discovery SE7 Tech help needed!
Ok I purchased a 2003 Land Rover Disco SE7....its my 4th Disco. The 3 before it were great, this one has been a headache.
It has 79,000 miles.
I bought it and while driving it home the check engine light came on. Took it to a guy who "specializes" in Land Rovers. He told me it was the MFA sensor. I replaced it myself. Next day light was on again and the vehicle stalled and would not restart. Had it towed to his garage. He said the valve cover gasket was leaking and ruined the Crankshaft Sensor. Has the valve cover gasket replaced as well as the Crankshaft Sensor for $500.00. Drove it home and guess what??? Next day I got a check engine light and a code P1701. The mechanic said it was the O2 sensors. He replaced them at $190.00. As I went to pick up the vehicle...anyone want to take a guess what happen? Yep! Check Engine Light! He said it was the wiring harness for the Mass Flow Air Sensor and replaced that. So I take it home and have been driving it for two days and now....CHECK ENGINE LIGHT!!!!
DiscoMike....you seem extremely knowledgable based on what you've posted. Any ideas??? Other than setting it on Fire?

You need to stop taking it to this guy, he is making his house payments with your money.
90% of all O2 codes on a LR are due to the need of a tune up, that means new spark plugs and plug wires.
The crank sensor going bad around your mileage is the second most common problem with DII's.
That is a $70 DIY.
The valve covers leak on all Rovers, you can fix them yourself for $5.
Go to Sears and buy a 8mm 12 point deep well socket, I assume you have a socket set, if not go buy a cheap one, $10 at AutoZone is all you need.
Every 6 months take that 8mm 12point socket and snug up all the valve cover bolts you can get the socket onto, no more leaks.
If you get us the trouble codes we can help you fix your truck, AutoZone will read the codes for free.
