I have an 01 zx3. it has been sitting for the past few months. I went to drive it the other day, it idles fine. Seemed to be going well. When i push down the accelerator, nothing. Dosent stall or anything, just seems to hold a steady slow acceleration. maybe a slight hesitation. It has an auto trans. If i shift it manually it runs great. picks up real nice. any sugestions would be appriciated.

DTC code definitions available here.

P1121 - Throttle Position (TP) Sensor Inconsistent with MAF Sensor
The PCM monitors a vehicle operation rationality check by comparing sensed throttle position to mass air flow readings. If during key ON engine running self-test the comparison of the TP sensor and MAF sensor readings are not consistent with calibrated load values, the test fails and a diagnostic trouble code is stored in continuous memory.
Air leak between MAF sensor and throttle body
TP sensor not seated properly
Damaged TP sensor
Damaged MAF sensor
Drive vehicle and exercise throttle and TP sensor in all gears. A TP PID (TP V PID) less than 4.82 % (0.24 volt) with a LOAD PID greater than 55% or a TP V PID greater than 49.05% (2.44 volts) with a LOAD PID less than 30% indicates a hard fault.
