My first question is what kind of plugs do most of you guys prefer?

My second question... which im pretty sure on my diag... but i got a ses for a high output and low output for a o2 sensor voltage... and when watching it in the datastream it would flicker between say 750mv and 790mv... and as well as show no data then flicker back... this tells me i have a bad o2 sensor... which brand do you guys prefer on them as well?


Thanks guys.

NGK TR55 or TR5....gapped to .050.......get a gapper tool and check them all.

Yes...bad 02 sensor. Denso part #2344025 16" wire. Measure to make sure that lenght will work. And YES, it will work in any of the four 02 sensor positions. Sensors are all identical, part numbers are different because of different wire lengths. They cost between $35.00-$45.00 each on Amazon.com and at rockauto.com.

GM dealerships sell this exact same, IDENTICAL Denso 02 sensor at the dealerships in AC Delco boxes for as much as $180.00 each.

Also... when i pulled these msd wires off i noticed they have started to crack open and reveal the wire... no good... explains part of the miss... and that i pulled bosch platniums out... with 4 electrodes

i already know what wires to run because i run them all the time with no issues... on anything from imports to 8.1 chevy trucks...

LS6427, are the Denso plugs the same as the ACDelco ones listed in the OEM part # sticky? To the original poster, Amazon claims that Denso 234-4087 is for the front right O2 and that Denso 234-4025 are for the other 3. I'm assuming this is simply because of the length of the wire?

length must be the only difference

Not sure about part #'s....I just know GM is contracted with Denso........GM uses Denso sensors as their own sensor at all dealerships.


And the 2344025 is just the long wire Denso.......all four 02 sensors in the four positions themselves are all identical sensors.

Any sensor will work in any position.
