New start-up help

[Steve Wood]

I would prefer a single wire Denso or Delco unit.  I never was convinced that the three and four wire sensors worked as well as the original sensors.

Also, if it still seems rich..remove the air filter and see if that has any positive effect.

Think it wouild be ok to use a single wire and just tie in to the signal wire of the harness?

[Forzfed]

I've killed a lot of Bosch O2 sensors!  I put a 3 wire in my low milage car and it's been really good.  Like Steve said, the Denso or Delco is all you need.  I have the Denso in my other car and it works great.

Should plug right into the original purple wire connector

[V6DVette]

But the original connector isn't there. Harness for the engine came with the four wire. Don't see why I can't splice into the signal wire and leave the four wire plug taped up do you?

[Steve Wood]

I never had a four wire sensor that worked quite right.  The three wire Delco sensors worked pretty well but they don't fail and code like the single wire sensors in many cases.  Instead they seem to lose range of voltage swing.

Bosch never lasted long for some reason.

The four wire is from Ford. I think Jag used them too so what do you expect? lol
I'll leave it be for now. Swap it out if all else fails.

[Steve Wood]

Yep, I was just trying to get it to a normal state that should work by eliminating the gimmicks...

[V6DVette]

LOL...There's nothing about this car that's normal. But I do agree about the gimmicks.

[Steve Wood]

25 years or so ago, we all tried them...don't see them for the most part these days.  I even had a Kenne-Bell intercooler fan shroud

[V6DVette]

Ya mean that doesn't work? 
How about the water cooled up pipe? 

[Steve Wood]

someone gave that to me as well, but, I knew that it could not work so I gave it to some kid who thought it was cool

[reality]

With that pipe and a little ingenuity 1 and 1/2 tenths and 2 mph. on my car. Maybe it wasn't all the pipe tho. And of no use on the street.

Man...you old guys had all the fun.

Meaning what exactly?
