My truck has been running wierd. When ever I drive it it sounds like its back firing and sputering. And does not have all the power it shoud. So I did the trouble code check and it came up with two codes. One was the throttle back solenoid. And the other is the EGR solenoid. And I dont know where to find those or fix them
When asking about an engine running problem, you need to tell us the engine size. You need to get the exact fault codes too. I assume you mean the throttle position sensor but fault codes never say to replace parts. They only specify the circuit or system that needs further diagnosis.
