Horsepower??

How much hp does the '88 2.2L convertible have?

Found some Information for you
The initial carbureted 2.2 produced 84 hp (63 kW), but the output was increased to 96 hp (72 kW) and 119 ft·lbf (161 N·m). Later versions were fuel-injected (http://en.wikipedia.org/wiki/Fuel-injected) and produced 99 hp (74 kW) and 121 ft·lbf (164 N·m), and a High-Output version (http://en.wikipedia.org/wiki/Chrysler_K_engine#High-Output_2.2) for the Dodge Charger (http://en.wikipedia.org/wiki/Dodge_Charger_%28L-body%29) produced 110 hp (82 kW) and 129 ft·lbf (175 N·m). Some were even turbocharged (http://en.wikipedia.org/wiki/Turbocharged) and are referred to as the Turbo I (http://en.wikipedia.org/wiki/Chrysler_K_engine#2.2_Turbo_I), Turbo II (http://en.wikipedia.org/wiki/Chrysler_K_engine#2.2_Turbo_II), Turbo III (http://en.wikipedia.org/wiki/Chrysler_K_engine#2.2_Turbo_III), and Turbo IV (http://en.wikipedia.org/wiki/Chrysler_K_engine#2.2_Turbo_IV). The plain fuel injected 2.2 L competed with Ford's (http://en.wikipedia.org/wiki/Ford_Motor_Company) HSC 2.3 L engine in the Tempo and Topaz, using very similar bore and stroke. Ford's HSO engine competed with the 2.2 Turbo versions.

In case you needed a more direct answer, the LeBaron convertible in 1988 had the fuel-injected, standard-output version of the 2.2L SOHC engine. According to Wikipedia (I don't have my books in front of me), the hp claim for that engine is 99hp.
