Hello Stevie. Nice to hear from you today! I'm sorry to hear you are having this problem. I know this can be frustrating. Was the reason to have the fault codes checked due to the check engine light coming on or any other warning light that had come on?

Just the check engine light

Thank you for your reply and that information as this does help me better understand the situation. Please give me one moment to type out some info for you. I’ll be right back! Thank you for holding Stevie! The fault code that is coming up is to let you know that the Nox [exhaust](/topics-exhaust-mercedes/) emissions sensor for bank 1 in the exhaust stream is acting up. The sensor is no longer able to read the exhaust properly so it sets this code. In order to resolve this issue the sensor has to be replaced as well as the wiring checked leading to the sensor for any wiring issues that need to be repaired. The cost to have the code properly diagnosed and the sensor replaced can cost around £300 in some cases. The vehicle can continue to be driven for now with no issues until it is replaced but I do recommend having it looked into and repaired as soon as possible.

I want to put a straight pipe with no muffler on my 2005 Chevy Silverado and keep the catalytic converter

This is caused by the transmission internal or solenoid issue. The transmission is trying to go into reverse and forward gear at the same time. Have the transmission tested for solenoid or other internal issues with transmissions.
