Limp mode no check engine light
Hey guys I have an 08 scion tc. Driving great then out of no where went into limp mode with no check engine light. It will idle like a sewing machine but will not go over 2500 rpm’s. I’ve already replaced the maf sensor, CSP sensor, all four plugs and coil packs. I have a throttle body and an upstream O2 sensor ordered. Any ideas would be appreciated thanks.

What 62fender said.
It could also be the injectors and they are badly misfiring. This has happened to me. I keep a couple injectors and coils in my ride and some tools to swap them out while on the road. Instead of having to wait for a tow to get me back home. Sometimes a coil will go bad on me causing a misfire or failing injector causing misfire. So I just swap them out quickly. Like changing a flat tire. lol
