O2 sensor help!!
Hey guys.. I’ve owned GMs all of my life.. sourcing replacement parts, and performance parts has never been an issue... until I purchased the 96 LT4 vette.
not only can I not find literally a single manufacturer for performance/lowering suspension, I can not for the life of me find replacement oxygen sensors. I can’t even find out how many I even have, to replace...
if anyone out there knows part numbers (preferably ACDelco) or how many I need, can you please speak up!! It’s driving me crazy!
hope all is well, and I appreciate the help!

Hi, I installed AC Delco AFS75 O2 sensors on my LT4 (50,000 miles). I was getting an intermittent PO152 (high voltage bank 2 sensor 1) code every now and then (it pointed to passenger side front O2 sensor). Replacing both front sensors took care of the code.
You have four O2 sensors, the front ones (bank 1 driver's side and bank 2 passenger side) are the most important for engine operation. The rear O2 sensors (bank 1 and 2 sensor 2) monitor the catalytic converters efficiency (hence they are mounted behind the converters).
You need to scan for codes and determine which O2 sensors are setting off codes. If you have over 50,000 miles change both together.
The sensors can be purchased from Rock Auto (lowest price) or Amazon (higher price).
If your looking for a great suspension package check out the Ridetech Coil over kit. I love my Ridetech setup, can't say enough good things about it.

You have 4 sensors on your '96. Two front sensors used to determine closed-loop fueling, and two rear sensors used to determine whether the catalytic converter is functioning correctly. They are the all the exact same sensor.
As Grandspt says, the ACDelco AFS75 sensors work fine and aren't that expensive. I got mine for $35 on Amazon last year.
As for lowering, Vansteel carries parts to lower C4s if all you want to do is lower it a bit. If you want to overhaul the suspension, then as Grandspt says, there are coilover kits from many companies, including but certainly not limited to Ridetech and Vansteel. However, as you have F45 suspension, do note that going to aftermarket suspension components will require bypassing the sensor connections at each shock. As I mentioned in your other thread, this isn't difficult or expensive to do, but it is something you must keep in mind.
