Reduce Engine Power
#1
![Default](/forum/images/icons/icon1.gif)
Ok so I got reduced engine power on my vehicle and I was unable to drive it faster than 5 mph. Throttle body and pedal sensor was replaced. 3 weeks passed and the problem came back except this time I could accelerate up to about 30 mph. This persisted and the throttle body and pedal sensor has been replaced 4 times. In addition the wiring harnesses, ground wire, and alternator has been replaced as well. This worked for about a week and the reduced engine power has come back again. Any suggestions?

I’m sorry you are experiencing this issue with your vehicle. What year is the vehicle? Where was the work performed?
