How does a bad catalytic converter effect the way the car run does it feel like the car is struggling to pick up speed?

A foul smell is the most common sign of a bad catalytic converter. If you smell what seems to be a rotten egg and it gets stronger over time, the catalytic converter is not working properly. A large drop in your fuel economy may be a sign that your catalytic converter is going bad or is blocked. A lack of power, especially at high speeds, may be a sign that the catalytic converter is going, or has gone, bad.A vehicle that stalls during idle, or idles rough, may have a blocked or bad catalytic converter. Your catalytic converter may be blocked if you experience bucking or hesitation while trying to accelerate. Additionally, your vehicle may run at a higher than normal temperature. A catalytic converter typically doesn't go bad without an underlying cause. A mechanic should be able to find the original problem and may not have to replace the converter.

You removed catalytic converter on a 1987 Pontiac fiero now the idle is real high service engine light is on Is there any kind of a oxygen sensor loop or something you can plug in to fix problem?

Removing the catalytic converter on your 1987 Pontiac Fiero can cause the engine control unit (ECU) to receive incorrect readings, leading to a high idle and the service engine light being triggered. One common solution is to install an oxygen sensor simulator or a dummy load to trick the ECU into thinking the catalytic converter is still present. Alternatively, you may need to adjust the idle speed manually or check for any vacuum leaks that could be contributing to the high idle. It's also advisable to have the vehicle scanned for trouble codes to identify any specific issues.
