If your 1991 Mercury Capri with a 1.6L engine smells rich, it may indicate that the engine is running too rich, meaning it's getting too much fuel relative to air. This could be due to a faulty fuel pressure regulator, a clogged air filter, or issues with the fuel injectors. Additionally, check for vacuum leaks that could affect the air-fuel mixture. Addressing these issues should help lean out the fuel mixture and reduce the rich smell.
What else can I help you with?
2000 mercury sable and the check engine light is on you diagnostic checked it and the code was 171 It read systems lean Any suggestions?
Fuel filter
What type of food people ate in the 1980s?

What can cause lean fuel mixture and?
A vacuum leak can cause a lean burn.
What is P0174 code on a 2005 Jeep Liberty?

What does the code po 174 mean on a 1999 Mercury Cougar?
The code PO174 on a 1999 Mercury Cougar indicates a "System Too Lean (Bank 2)" error, meaning the engine control unit (ECU) has detected that the air-fuel mixture is too lean on the second bank of the engine. This can be caused by issues such as a vacuum leak, a faulty mass airflow sensor, or fuel delivery problems. It's important to diagnose the underlying cause to ensure proper engine performance and efficiency.
P0171 AND P0174?
lean bank 1 lean bank 2 fuel trim limits reached
What does fuel to lean means?
basicly its changing the mixture of fuel/air to improve performance
Can a rich fuel condition cause a lean afr reading?
Yes, a rich fuel condition can sometimes cause a lean air-fuel ratio (AFR) reading due to issues with the oxygen sensors or the engine's fuel management system. If the engine is consuming more fuel than intended, but the sensors detect an excess of unburned fuel, they might incorrectly adjust the mixture thinking it’s lean, leading to a lean reading. Additionally, other factors like exhaust leaks or incorrect sensor placement can also misrepresent the AFR, making it appear lean despite a rich condition.
What causes an engine to run too lean?
An engine runs too lean when there is an insufficient fuel-to-air ratio, meaning there is more air than fuel in the combustion chamber. This condition can be caused by a variety of factors, including a malfunctioning fuel injector, a clogged fuel filter, a vacuum leak, or a faulty mass airflow sensor. Additionally, issues with the fuel pump or a weak fuel pressure regulator can also lead to a lean condition. Running too lean can result in poor performance, overheating, and potential engine damage.
What is diagnostic code 51 in a 1997 Jeep Wrangler?
51** Fuel System Lean A lean air/fuel mixture has been indicated by an abnormally rich correction factor
What is p0174 for Lexus?
Fuel injection system fuel trim too lean (Bank 2)
What causes lean fuel mixture?
A lean fuel mixture occurs when there is an excess of air relative to fuel in the combustion process. This can be caused by factors such as a malfunctioning fuel injector, a vacuum leak, or improper tuning of the engine. Additionally, environmental conditions like high altitude can also lead to a lean mixture, as there is less oxygen in the air. When a lean mixture is present, it can result in higher combustion temperatures and potential engine damage if not addressed.
