Hey Guys!
Got my first Disco 2 month ago...Ran fine until a week ago on my way home it suddenly stopped accelerating properly...when pressing the pedal rpms go to 2000-3000 and going 15-20mph max...Got the codes read and got the following:
1300, 0734, 0733, 1590, 0171, 0130, 0150 and 0300 along with every cylinder listed separately (0301,0302...0308)
It idles fine, when I put it to drive rpms fall to about 400 and I get that little shake
Slowly got it to work, where I can get it into a garage type of space...changed the spark plugs to Bosch+4 with Bosch wires (will change to magnecors later), changed the transmission fluid with dex III and a bottle of lucas(thanks to the forum!!!), washed the MAF with MAF cleaner...Obviosuly no change but would have to do those things anyway.... A "good faith" mechanic, after looking at the car and the codes mumbled something about electronics and sent me to a shop specializing in diagnostics...
I have 101k miles on it, filling 93, no history on what has been done to it before

 

Forgot to mention...its a 2000 Disco II, got it when it had 97k, right now have 101k.....Thanks in advance!!!

 

After changing the plugs, wires and cleaning your mass airflow sensor, did you reset your codes and check again to see if you have a different set. Is there a difference in performance after the work that you did.

P1300 is an ignitor circuit malf. the rest are cylinder misfires and transmission codes. I need to check the code table, this is from memory.

 

Make sure you have exhaust coming out of the tail pipe - you could have clogged catalytic converters.

 

Could feel the new plugs but overall no change....haven't reset the codes after changing...should I clear them and just check again (just bought the diagnostic computer, not really familiar with the process)....

Yeep the smoke is coming out!!!

 

Absolutely, clear the fault codes then operate it and see what are your new codes. What concerns me is the misfire codes on all you cylinders, if the truck was driven like that for a while than your converters are clogged causing back pressure to build up, Night train makes a good point.

 

First of all, you never try to clean a Bosch MAF, it will kill it every time.
So strart with a new MAF, that will clear the 734, 733 and 171 codes. Once you have done that get those wires installed and you should be set.

 

Thanks Everybody!
Will start with clearing the codes and checking if a different set comes up, once I get home from work....will post the results once i get them
Will order a new MAF and Magnecor Wires.
Anybody has any ideas on the 1300? could that lead to all cylinder misfires or it just needs quality wires?

 

Emission misfire!

 

Decided to stop by the engine diagnostics shop on my way home...On my way there started getting clapping noise (thinking its catalytic converter that got clogged), looked under the car both are RED HOT... Got to the shop and these Russian guys don't have any tools over there except computers....Paid $100 for the diagnostic, they did not share the results but told me the problem was in the ECU...they offered to fix it...I decided to give it a try...2 hours later I pick up my Disco and it never ran better!!! Though I still get the 1590 (ABS), 0150, 0733, and 0171 (the MAF). They told me to come back in a week and they will try to tune up the MAF with a computer...The engine and the tranny is good according to them!! All together I paid $450...
Anybody have any ideas???
