Altima 2002 will not rev higher than 1000 rpm and will not drive faster than 5 mph. No noise or anything preceded this happening. Car was operating normally then after light I stepped on accelerator and the car had no power. It only revved to about 1000 rpms, and drove at 5 mph. If I talk for if accelerator the car idles fine. If I step on gas it tends to 1500 that's all she does. If I step on and off accelerator it will repeat the same as above. Any thoughts? Tranny or throttle Boby issues? Thanks.
It sounds like a sensor issue. Is the check engine light on? It could be a throttle position sensor. If the check engine light is on, have the computer scanned to identify trouble codes. Most parts stores will do it for free.
