First start runs fine, couple minutes later rough idle. Codes are P0113, P0171, P0174, P2196, P2197. Cleaned MAF, checked and replaced3 small vacuum hoses and cleaned throttle body and tried water test on intake and vacuum areas. Still have same problem except fuel smell is way less then before

Check condition of battery including load test, a low battery will cause multiple codes. However it may be a pcm problem with the 2196/7 codes so a pro will have to look at that if battery is ok.
