4.0 SOHC bogging @ cold acceleration

[Drewmcg]

I have a 2010 4.0L V6 XLT that I bought used last fall @ 116k miles (now @ 125k) with a newer, professionally-rebuilt trans.

For the first 3-5 minutes or so after startup, I get bogging on acceleration.

What should I look at first? Dirty IAC valve? Dirty throttle plate? Thoughts? TIA.

There is no iac valve. Do you have a scan tool with live data? Also any codes?

Thanks; I'l check for codes (no CIL illuminated). Dealing with a brake (booster?) issue today . . . .
