Dealing with a 2005 2.7 with about 200k on it.

The car wil stall at random times. Always happens at slow speeds, usually while trying to add small amounts of power. If you add a lot of power it will not stall. It sometimes has hesitation choosing which gear to downshift into as well.

Have replaces all spark plugs, and TPS. Looking at possibly CPS. It has seen several mechanics, no one has been able to diagnose or fix it.

No check engine light.

Anyone have ideas?

 

Clean in-take plenum, re-gap spark plugs, put in couple of bottles of injector cleaner
Only a guess
Could be something else??
