okay today i was washing my Pontiac grand am gt 1999, and i was running fine before i started to wash it, then when i got to the engine, i put a degreasser on it let it sit for about 5 minutes and from there i got to water hose and hosed it off, as soon ass i started it, it felt like the car was just chuggin along an didnt get up to speed quick, and to make matters worse it started to smell like something was burning, can you please help me figure out what the problem it is?
