Hello Scotty I have an Honda civic coupe 2005 manual with 135,000 miles on it and it has a problem that every time I try to pass another car in the highway it hesitate a lot and I though it was the throttle but I put a new one with all its valves and it didn’t solve it I though it could be some electrical problem but an electrician checked it and everything was normal what do you think it can be?

dirty or out of adjustment valves often do that. Try this video and have the valves checked to see if they need adjusting https://www.youtube.com/watch?v=cP7D-5iQcNo

Ok thank you i’ll check them and another thing if its not the valves the problem do you think the gas pump may be check by the mechanic as well?
