Drive straight to Automobile Diagnostics in Columbus if your automobile is doing the things we are going to list below. Unfortunately, these problems indicate that someone has stolen the catalytic converter from underneath your automobile. People cut this exhaust system part away from vehicles all the time because they want the metal out of which it is made.
Loud and Roaring Engine
If your engine is loud and roaring when you turn it on, you likely have a missing catalytic converter. Although the converter is not a muffler, it absorbs some of the engine’s noise and the sound of the exhaust being forced out of the engine. Consequently, when it isn’t there, your engine will roar loudly, especially when you apply the gas.
Speaking of applying the gas, your acceleration will lag and jerk when you press down on the accelerator. This is because the missing catalytic converter cannot take the brunt of the exhaust being forced out of the engine. Consequently, your vehicle will respond to this force by jerking when you try to pick up speed.
Speaking of picking up speed, a strange symptom of a stolen catalytic converter is your vehicle’s inability to run smoothly when you are driving slowly. It will run just fine when you are driving faster, but the engine has problems producing low-end torque without a catalytic converter. Consequently, your automobile is going to sputter until you reach a higher speed.
Check Engine Warning
The engine problems discussed above and the fact that the catalytic converter is missing is going to cause the engine control unit to turn on the check engine light. There will be a series of errors going back and forth between the engine control unit and system sensors because things are operating correctly without the catalytic converter. Because the engine control unit cannot replace the catalytic converter, it will turn on the check engine light so you know something is wrong.
Noticeable Exhaust Odors
Finally, we said in the introduction to this blog post that you should head straight to our shop, but, realistically, it’s safer to pull over and call for a tow truck. Your vehicle’s exhaust will be pushed out of the engine and have nowhere to go but inside the passenger cabin because the catalytic converter is missing. This can make you sick because you will inhale carbon monoxide.
