my wife was driving the LR4 today when it went into Restricted Performance Mode. she made it to a parking lot where i met here and checked a few fuses and tested the battery. everything looked good there. my Foxwell NT had some issues communicating with the ecu/bcm, so never was able to pull the codes.
however, after restarting the vehicle, it ran fine and was back in its normal mode. i drove it for 20 minutes and no issues.
some quick reading suggest MAFs and/or fuel pumps. at 142,000 miles i can see it being either or both.
aside from getting a code reader that can communicate with the LR4 better, what else should i be looking at? should i do the MAFs as preventative maintenance? fuel pumps?
