94' Cobra Loss Of Power When Warm?

[BranSVT]

Been having an issue with my 94' cobra. Original 5.0, stock upper/lower, old autologic chip, SVO Aluminum heads, cammed, BBK Cold air. Runs great for the first 5-10 minutes, pulls really hard starting at 2300-2500 RPM, then when it gets warmer, I only make power around 3000+ RPM and it also feels like some power was lost. It even has a different exhaust tone. Any ideas?

Check your intake air temp sensor. Or the engine coolant temp sensor. Sometimes they don't cut on the engine light. Sure there's info to check them somewhere on here. @jrichker.

o2 sensors are also suspect if your closed-loop behavior is significantly worse than open-loop.
