Car won't go over 45 miles hour check engine light on trottle body and peddle sensor i just replaced 2 months ago

Hello, "that's what's coming up again" - what is coming up again? What trouble codes are being set? What testing is being performed based on the codes? Codes provide clues for testing to be performed. They never specify failure of specific components. As a result, it's necessary to troubleshoot and determine the cause of the codes being set. Perhaps it's related to one of the recently replaced components, but perhaps not. Hands on testing is needed. https://repairpal.com/auto-repair-near-me
