New O2 Sensors: Which to buy?
 

Hi,
Ok, my car pretty much has all the symptoms related to bad O2 sensor: surging idle (has died a few times when started up, but idles fine once started again), frequent "Check Engine" light, and it's hard to notice now but I think I'm getting bad mileage.

I've tried adjusting TPS and put in a K&N cone setup w/ RAM-AIR (not that I was expecting K&N to solve things).

Anywho, I'm looking forward to buying new O2 sensors this spring/summer, and I want to know what brand/model I should buy, and how much it will cost me per sensor. Also, I'm planning to install the sensors my self, and I want to know what I should consider before changing them myself.

My car: 1989 5.0L LX, cat-back exhaust (Prolly Flowmaster or Mac), 3.55 gears, and modified cam (not sure on cam details). It also has about 96,500KM (60,300 miles).

Thanks!
Bye!

When I've changed mine (yes more than once for various reasons) I've used Ford's O2 sensors. They are about $40 USD each.

Install is very easy. Just get yourself a 22mm open-ended wrench (I think it's 22mm) and take off the old ones. Then put a little bit of anti-seize compound on the threads of the new O2 sensors before screwing in the new ones.

Make sure not to get any anti-seize compound on the sensor tip.

Install should take about 15 mins.

Good luck. http://www.mustangworks.com/interact...oard/smile.gif

Bosch makes Fords O2 sensors.

Yeah, Ford's are Bosch. I think those are pretty much standard in the industry. Most are pretty pricey since they use platinum for some reason. *Shrugs*

It is a 22mm, but I read that you can also use a 7/8. Easy as pie, but don't forget the anti-seize. Oh yeah, Mustangs Unlimited carries them for your car for $54.95 each.
