I drive a 2003 chevy trailblazer. i just cleaned the throttle body and now im having serious drag on the engine, and it stops abruptly when i take my foot off the gas. i cleaned it and replaced it the right way, the only thing i can think of is that to get to the two bottom screws on the throttle body i had to remove two of the coils above the spark plugs. what could be causing this?
