Engine Performance problem
2000 Toyota Corolla 4 cyl Automatic 152000 miles

Very sluggish starting from a stop at times, especially when cold. Just replaced plugs, cleaned throttle body, replaced air filter. Which sensor would cause this (tp, ect,....)?

Many sensors could cause it, but you should have a check engine light?

No check engine light. It only happens when cold and when just starting from a stop the first time; press on gas, and it takes a few seconds to respond.

Measure fuel pressure with mechanical gauge and spark with a calibrated spark tester.

Sensors, like TPS, IAC, Coolant would set a code if out of range.
