Hey I have a question sir I have a 2010 Camaro with a 3.6 L engine we just replaced the motor with a used engine that has 32k on it. The new engine is going to reduce engine power mode and it’s misfiring and the code it giving us is fuel injectors. The engine is running real ruff going to limp mode due to misfire
well, check the injection system first, especially wiring which may have been damaged during all that work. PRAY you didn't get a bum used engine. Do a wet and dry compression test to check the engine out first, cause I see lots of bum used engines these days.
