Why does your 01 GTP rev to only 4150 rpms?

If your 01 GTP is revving to only 4150 RPMs, it could be due to several factors. One common reason is a fuel or ignition issue, such as a clogged fuel filter or faulty spark plugs, limiting engine performance. Additionally, the engine may be entering "limp mode" due to a detected fault, which restricts RPMs to protect the engine. Checking for diagnostic trouble codes (DTCs) can help identify the specific issue.
