Unmetered air entering the system before the Bank 1 or Bank 2 O2 sensor will send a false lean reading to the ECM. This could cause the ECM to extend the fuel trim. This could cause eccess fuel to pass through the catalaytic converter. This could cause damage to the catalytic converter. If the fuel trim stays below +25%, the check engine light may not illuminate so the problem may go undetected until the cat gets ruined.

Does a cracked manifold in a Renault Megane affect emissions?
If you are referring to the exhaust manifold then it should not affect emissions as the o2 sensor is after the exhaust blow it will adjust emmissions accordingly
Will 283 exhaust manifold fit a 305?
Yes, a 283 exhaust manifold can fit a 305 engine, as both are part of the small-block Chevy family. However, there may be minor differences in bolt patterns or exhaust port shapes, so it's essential to check compatibility. Additionally, using the 283 manifold on a 305 may affect performance due to different flow characteristics. Always verify fitment and consider modifications if necessary.
Can a hole in the exhaust manifold cause an evap code?
A hole in the exhaust manifold can lead to an evaporative emissions (EVAP) code, but it’s not a direct cause. The hole can create a vacuum leak or alter exhaust flow, which may affect the vehicle's overall emissions system and trigger codes related to EVAP system performance. Additionally, it may cause issues with the oxygen sensors, further complicating emissions readings. It’s essential to address any exhaust leaks to ensure proper functioning of the vehicle’s emissions systems.
How does the exhaust system affect car performance?
An aftermarket performance exhaust can free some of the power in your engine. These systems allow for a quicker, more efficient path for exhaust gases to escape. This means your engine "breathes" better.
Can a cracked exhaust manifold cause the check engine light to come on?
Yes, it can affect the oxygen sensors and catalytic converter.Yes, it can affect the oxygen sensors and catalytic converter.
What does size and shape of the exhaust and intake ports affect?
It affects how the engine breathes. The better it breathes, the better the performance.
Is a cracked manifold dangerous to drive and is it expensive to fix?
Yes, a cracked manifold can be dangerous to drive because it may lead to exhaust leaks, which can introduce harmful gases into the vehicle's cabin and affect engine performance. Additionally, it can cause overheating and further engine damage if not addressed. Repair costs can vary significantly depending on the vehicle make and model, as well as the extent of the damage, but it can be quite expensive due to labor and parts involved in replacing the manifold.
Can cracking your fingers affect your martial arts?
No, it will not affect your martial arts. There have been no proven studies that cracking joints will have any long term affects.
Can you cut off your exhaust after the catalic converter?
Yes, you can cut off your exhaust after the catalytic converter, but it may have legal and performance implications. Removing or modifying exhaust systems can lead to increased emissions, potentially violating local environmental laws. Additionally, it may affect vehicle performance and sound, possibly resulting in a louder exhaust and changes in back pressure. Always check local regulations before making such modifications.
Does fasting affect performance or performance affect fasting?
fasting affect performance
What size is the egr tube nut on the exhaust manifold of a 1997 vortec 5.7?
The EGR tube nut on the exhaust manifold of a 1997 Vortec 5.7 engine typically requires a 15/16-inch socket for removal. It's advisable to ensure proper fit and clearance when using tools in that area due to space constraints. Always check for rust or corrosion, as this may affect the ease of removal.
Can to big of an exhaust affect performance?
Yes. In newer vehicles the exhaust is designed to match specific harmonic waves setup in the exhaust pipes along with specific flow rates of gases. Increasing or decreasing the length, radial size or the bend locations in the exhaust pipes can lead to hotter temperatures, lower efficiency and more wear on the engine (especially at the valves.) Older vehicles (75 and older) tend to have less problem with exhaust changes as the system was designed to higher tolerances and less precise performance.
