Wife's Disco Died, need help
My wife drives a 2003 Disco with 80K miles. Its the base model and in very good shape.
Every so often we get the 3 amigos, a restart usually clears them.
Occasionally we get a CEL. I have a wifi ELM and read them with my I phone. I believe they were misfire related, but I cant recall the exact codes.
A week or so ago she was going shopping and pulled in to get gas. When she went to restart the car which would barley run, had no power and would not rev up at all.
She nursed it to a Garage 1 block away and got a ride home, I was out of town.
The mechanic at the garage initially thought it was a bad fuel pump and swapped it out. No joy
He said he could keep it running but the cat's heated way up.
He pulled some codes and said he got several misfire codes and an MAF code,
He tried a MAF next again, Nothing.
I stopped by today and we tried to start it, the truck would barely run
Thought I would start a thread here for some assistance.

I'm curious, how does your mechanic justify the parts he has installed which did not fix your problem?
It seems weird to me that you take your vehicle to a mechanic because they are professionals, yet they can't diagnose your vehicle without wasting your money.
There should be some recourse.

There is a fuel filter under the right part of the frame on a D1. D2 ? but change the fuel filter.
Might be the Crank position sensor acting up. But that only acts up usually when the engine is hot.
If the cats are heating up yes then excess fuel. Maybe one of the coil packs is going out.
You may want to put on an OBDII with live readout and see what is going on.
Also make sure the TEMP sender is sending the correct temperature to the engine computer. This is a separate sensor than the temp gauge.
Pretty much the inputs to the ECU computer are
Throttle Position
O2 sensors
MAF readings
Crank position
Temperature from Engine coolant
Temp from ambient air
All this has to line up.
Might be the throttle position sensor too.
But you should get codes for these.
Actually, this may sound stupid - but you may have a low voltage problem.
Replace the battery.

P1668 is an immobilisation code. That could well be the source of one of your problems.

The misfires are tricky. Lots of possible reasons for them.
