My 2002 Nissan won't accelerate but it starts up fine, it idles fine.

Check engine light on?

No ck engine light. but when i scanned it, 1 code & it said 1 gear ratio was off. when i first start it up it will lightly accelerate just for a moment then go limp. If i hold the paddle down to the floor, its surges a little.

Throttle plate assembly. This item is large blocky and will be in the air intake just prior to air entry to engine. Nissan may need to program it for your car. Dealers these days......

Thanks

2002 niss Altima has same problem
