post welding surge

[carbed 85 gt]

Help me guys I had my tailpipes welded to thy catback and now the car surges a small bit but seems to be getting worse.

Before the car was a solid idler. I know i forgot to pull the battery and grounds so maybe am thinking O2 sensors.

See "Surging Idle Checklist for help with all your idle problems. The first two posts contain all the updates to the fixes. I continue to update it as more people post fixes or ask questions.
