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 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
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?

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.
How do you fix a lean condition?
Give engine more fuel
