impala 2006 intermittent loss of power
hi, i have 2006 impala which is giving me hard time, it have 67k, and intermittent loss of power.
it suddenly lacks power with message of INSUFFICIENT ENGINE POWER in dash. after like 3-4 cycles of ignition switch and starting it runs good again.as far DTC are concerned it had p0101 and p0201 which are for IAT sensor which i have already replaced with brand new. and as far p0201 is concerned i have checked ground pulses they are fine, since the problem is intermittent, i tried to compare the loss of power by removing IAT harness and also Injector 1 harness but nothing was similar to the actual loss of power condition. if anyone have any idea what could be wrong ??
could it be throttle position sensor ? but no DTCs other than 0201 and 0101 any help , any idea.
or can you please give me Wiring diagram for this model plz i really need it.

RE: impala 2006 intermittent loss of power
after struggling with my car for one month as no one seemed to know what was wrong with it.
Finally i have found it !!!. TAC Motor was at fault. so i had to change my TAC unit cost me 100$.
now its running good for whole week with no problems.
how i found it, i talked to CAB Drivers as in my city almost 70% cabs are of impalas, asked them if they had any problem like this and all answered the same as they have already changed TAC motor unit twice. Thanks to professinals
