Ok i have the autometer AFR gauge and at first my car ran rich almost all the time. but now even at full throtel its in the stoich. do you think this is a bad o2 sensor or somthing else?

 

First of all, how old/ how many miles is the one in the car now? Second, you can also use a meter at the O2 sensor input at the ECU to double-check the A/F gage. Stoich should be at the .4 to .5 volt range...

 

i wish i new how old the o2 was...but i bought it used and didnt ask the guy when i bought it. and thanks for the advice.

 

They're dirt cheap for about twenty bucks. Get a Bosch. Righty tighty...lefty lucy. Crimp your own connector on the wire.

 

Bosch makes a unit that plugs right in to our harness, Hailers (no splicey-dicey needed)...Wish I would have memorized the part number for it now, this comes up every other day

 

also my car hesitates at higher rpms...i know its not the clutch cuz i just got a new ACT one. do you think the o2 could cuase that. or is that somthing completly different??

 

The last time I looked, they jack the price up for that simple connector by a good five bucks. Five bucks more for a connector? No way Jose.

 

Lucky SOBs. When I checked it was $20 for the "universal" sensor and $40 for the "OEM" sensor.

And right now it's not running on any, because it's not running. :-) I plan to replace it once I get things back together, though.
