we just took our poorly running rover to autozone to get the codes pulled.
here they are:
P1590
P1171
P1174
P0171

thanks for the help.

mike,
i was gonna call you but im on my way to a 2 week field problem at yakima, WA and the wife will be taking care of the rover while im gone. so the diagnosis is gonna hafta be via e-mail. that and i lost your number when i changed phones. oops...
thanks

 

The codes I could find are all pointing to the engine running too lean. When was the last time you did a tune up?

 

last tune up was done around x-mas time. new plugs/wires and 60k service stuff.
i know one of those is the O2 sensor(s) but what else do i need to replace? the rover is running VERY poorly...

thanks

 

The 1590 is a rough road/ABS code, take it your 3 Amigos are on.
Need to check for vacuum leaks and air leaks between the air filter to the t/body.
I might be leaning towards a MAF but wouldn't suggest replacing it yet unless more codes show up.

 

This is Brian's wife,

So what exactly is it that I need to be looking for? Mike could the things your thinking is the problem, cause all the power loss, Dieing while in motion, Can't go above 2000 RPM or over 30 MPH, And when she loses power she either dies or all the sudden jolts forward real fast and gains power again until she decides to lose power again or die.

 

Normally not, usually those codes will cause a poor running engine but not shut it down. Crank sensor is the main cause of a Disco having the engine shut down or be hard to start.

 

That is very poopy. Cause she is having trouble starting and is shutting down. Our poor baby. I will let Brian know the Diagnosis. What is the easiest way to fix our problem? i know it's going to cost and arm and a leg.

 

Ok. So he wants to know what the part numbers are and how much each part he will need will approximately cost us, and the easiest ways to install them.

 

You may want to e-mail me your tele number so we can talk.
