I have a 2003 Discovery with 87000 miles on it and it keeps throwing 2 codes. The P0134 and P0150. I have recently changed the front O2 sensors with two I bought off ebay for about $30 a piece (see link below). Before I changed them, It was throwing codes P0130 and P0150. I think it may have something to do with the vibration I'm having that starts at about 25 mph. It doesn't vibrate while cruising at 55mph, just when I give it some gas. Anyone have any ideas? Cheap O2 sensors?

Can you say "JUNK", you can't cut corners when buying 02's.
Do you have a scanner that can read the output from the 2 sensors, are you still getting any codes since your replaced them?
Did you clean all the oil from the connections?

 

Mike, I did clean the oil from the connectors and put die electric grease in them when I installed them. I'm still getting P0134 & P0150. My scanner does not read the output from the O2's.

Which O2 sensors should I buy? Or should I invest in a new scanner?

Thanks,
Jason

 

You could have spent $20 more and got legit Bosch ones from a much more reputable company (amazon)

 

there is someone in the for sale section that has a pair from amazon that they don't need, he's asking almost the same but I'm sure you could talk him down to an agreeable price.

 

I just did the Walker o2's. Got them on ebay for Miami British for 130 shipped. Atlantic British sells the same ones, but the dont tell you theyre Walker.

But if you get a better price on the Bosch ones go that route

 

You can only put on Bosch O2 sensors.

Those ones you bought on eBay - open a case and return them.
They are Junk as Mike said.

 

Thanks guys. I will be ordering new ones.
