Hesitation

Car had issues about hesistation on acceleration. More like cutting out every second then continues to accelerate all the way to higher rpm's.

In every gear, almost feels like a TCM issue.

Found that camshaft actuators we're broken, timing chain was noisy and had major play.

Felt like the vehicle was in limp mode.

Since the repair I have put in a throttle body, a used TCM, had the ECU and TCM all updated with newest software. Mass air flow sensor, pressure relief valve, vacuum tested the turbo and waste-gate. (All working within specs). No shaft play and waste- gate opening normally and really accelerating okay, just cutting out every second as a pause.

Codes are currently only in the system but no check engine light ever comes on:

P2504 Charging system to high
U0121 Abs modual lost communication

Hello,

This sounds like a misfire and a plugged catalytic converter which will restrict exhaust flow causing the low power you are describing. Here is a guide to confirm the problem. Have you installed new spark plugs lately?
