Raw gas coming out of the tailpipe on a 1991 Mercury Capri could indicate several issues, including a malfunctioning fuel injector that is leaking or stuck open, leading to excessive fuel entering the engine. Additionally, a faulty engine control unit (ECU) or a defective sensor, such as the oxygen sensor, may cause improper fuel-air mixture, resulting in unburned fuel exiting the exhaust. Another possibility is a clogged catalytic converter, which can lead to back pressure and incomplete combustion. Lastly, issues with ignition components, such as spark plugs or ignition coils, could prevent proper burning of the fuel.
No. A bad head gasket would cause water to come out the tailpipe. You will see white smoke. Leaky rings would cause oil to come out the tailpipe. You will see blue smoke.
The model year info would help.
In 1973, the Mercury Capri had a starting price of approximately $2,500. This price could vary based on optional features and trim levels, which would increase the overall cost. The Capri was marketed as an affordable sporty coupe, appealing to a range of buyers during that era.

As of my last knowledge update in October 2023, specific data on the number of 1991 Mercury Capri vehicles registered in the U.S. is not readily available. The Mercury Capri was produced in limited numbers, and many may no longer be on the road. For the most accurate and current registration statistics, checking with the National Highway Traffic Safety Administration (NHTSA) or state vehicle registration databases would be necessary.
the speedometer is based off of a gear in the tranny that spins.
Excess fuel causes black smoke.
May be a bad fuel pressure regulator.
Capri is a small island. There are no cities on Capri
