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?
have the same problem?
