Spliced O2 sensor
Spliced O2 sensor I looked over my car and seen that I had o2 sensor pigtail had been frayed. Well I went back spiced it back together. My question is will it work even if I spliced it back together will that work or will the o2 sensor still not read correctly because of the splice.
It is iffy at best, 02 sensors make fuel adjustments and they are outputing millivolts, any type of splice in the connection can cause a slight increase in resistance, it does not take much resistance to chang the output buy a few millivolts, which will throw your fueling of.

sorry, your right. wasnt thinking clear. Just trying to say that the car might seem to run fine but i think the A/F would be off. If he's lucky the bad wire is just for the heating element in the o2 sensor
hmmm sorry to steal the thread but quick ? ...I have a slight miss on 3 &4 cold ...give it some throttle then no miss....when hot at idle I have a miss on 2&6 I THINK, I foget which 2 they were but they were different then the cold miss. again give it throttle and no miss. When I made my 02 extensions I used a plug with tthe wire out of a junk car and get the other plug end soddered them togther and shrink wrapped it...when you say that if its off at all it will screw the fuel up ...can this be why? are my symptoms a result of this...?
MagnaTransAm you'll want to replace your home made extensions with good quality o2 extensions. The LS motor is always reading the o2 sensors, and a poor quality extension can mess it up. You might have other problems in regards too the misfire, but replacing those extensions means that's one more thing you can rule out when trouble shooting.
