bobby, that is the Mass Air Flow sensor.
I was throwing faults on my disco maf, bought a good used one on ebay, ($40 - $50) cleaned mine w/maf cleaner (2 min.) & been fine for months now. I'm keeping the 2nd as a spare as they can be fragile.
The whole job took 15 min. with a screwdriver.

 

That is the part, their price is just too high.
Call me tomorrow and I'll tell you where you can buy it for APX $125 shipping.
By the waym that particular MAF does not clean well so don't waist your time.

I'll call tomm. Thanks Mike ps. any time better than another to call? Bobby

 

Wanted to give a quick THANK YOU!!!!!!!!!!!!!!!! for saving me time,money, and sanity. I got the sensor for $125 and changed it myself in 5 mins. Car is running GREAT and my ambient lighting is gone!!! Also it has triggered me to fix alot of other little, but expensive at the mechanics, problems with the car. Feel like I have a new 2000 RR. THANKS AGAIN!!

 

Glad everything worked out.
i just got back from the shop this afternoon, I get to have my head gaskets done next week, looks like I get to take another shot at my extended warranty company.
