1. Thank you for the info on how to do the fuel pressure test

2. Sorry for the misinterpretation, I will double check the gaskets to make sure I have not pinched anything

3. The sensors I purchased came with the appropriate connectors, so I didn't need to do any soldering

3. Id like to get a good consensus on the brand of sensors I should buy before I purchase them, also where can I find OEM sensors?


Thanks again

Christopher

Honestly, as long as you buy decent OEM Sensors then so be it? I swear by Bosch but as Red said, he's had problems with his out of the box, and so he goes with Walkers. In the end, this is one of those items you get what you pay for and of the few items on my vehicle where I splurge, this is one of them. The last time I bought Bosch OEM Sensors (x4 new ones about a month ago for the E36), I found my lowest price online and then went to Autozone with the P/N and that price. They price matched it and I was out the door. This could get you out the door for relatively cheap with a set of Walkers...

For you consensus:
I use Bosch in my BMWs & Rover, and NGK in my Rubicon.

There are also plenty of threads on the forum where you can look up the +/- of each and decide which you want to go with. If my truck had Walkers on it when I bought it, I probably would have just stuck with those because I'm superstitious that way. I just wouldn't use something that someone reported did OK once upon a time?

Problem Solved!

I bought and installed a set of Bosch O2 sensors.

I am no longer running rich, and I am now getting about 12 to 13 mpg.

The check engine light remains off after a month, and my truck is running better than ever!


Thank you all for the information and guidance, I would likely still be throwing the wrench without it

Same problem as the OP same setup except:

1) I removed the cats and replaced them with fake cats
2) Front 02 sensors are Bosch. Rear 02 sensors are Walkers.
3) No codes

I'm getting 5-6 MPG maybe less.

No clue why.
