TPS adjustment is critical on these engines and you don't just turn it and lock it down. The adjustment needs to be set using an ohmmeter and a set of feeler gauges. The closed throttle position switch is "learned" on these engines, so that has to be relearned after the adjustment. I'm attaching a TSB that describes the procedure, however, use the measurements for the R50 Pathfinder for the VG33E motor as the D22 Frontier specs are for the KA24DE (the only available engine for the D22 Frontier at the time of the TSB's release).
