o2 Sensor question I have a built up 355 that is kinda runnin rich. Also when it first starts up when its cold it cuts out a little. When it gets warm its just fine. It runs a little rough in town as when it shifts in to overdrive it runs real rough kinda shakes. I have hooker headers and people are telling me i need front o2 sensors and that would help my problem out. Any advice?

[QUOTE=RamAir95TA;14179999]If you don't have O2s the PCM will default to fuel delivery on a "best guess" scenario. Additionally, your SES light should be screaming at you.[/QUO
I do not have o2 sensors at all they were deleted when the last owner put hooker headers on it and the there is no check engine light at all. It has been dyno tuned could that effect the deletion?

Without knowing what has been done in the tune it's kind of hard to draw any conclusions. But not having O2s on a setup like yours makes zero sense.
Additionally, what are your mods?

And all the mods i can think of is its 030 over with everything needed, ported and polished heads, roller rockers 1.6, lt4 hot cam, lt4 intake, headers, cold air intake, uhm it was totally rebuilt in 08, had a electric water pump that quit on me i went back stock due to money, and thats what i can think of. Its also been dyno tuned a while ago back when the motor was built.

The bung is what the O2 sensor threads into. In reality a bung is the plug on a drum barrel and the female part of the drum is the bung hole. You can use a spark plug thread chaser for the bung hole. definitely get something to screw into them while you have them welded up so they don't get fubared
