2001 isuzu rodeo 3.2 5-speed

I have a 2001 Isuzu rodeo 3.2 V-6 five speed with 180000 miles on drive train when I start it cold, it will only idle for the first couple of minutes. if I try to press the accelerator before it warms up it pops and sputters will not rev up. after it warms up it runs fine. it still has a P1340 code. when problem first started, it had that code and P0101, P0300, would barely run and would die when idling . I have cleaned all o2 sensors, EGR valve and checked EGR function it works, I have also cleaned MAF sensor, and checked it in live mode with innova OBD2 scanner, and cleaned throttle assembly, changed fuel filter. I have also checked for vacume leaks with carb cleaner while engine is running and did not find any leaks. what else can I try
