Newbie Honda Street Owner - Loss of Power at full throttle

    Hello, I’m a total newbie so I apologize in advance for not knowing anything. Any help or guidance would be greatly appreciated.


    This past Friday I purchased a 1990 Honda Street (Chassis: HH4-1024733, Engine: E07A, Manual Tranny) from a dealer in Mississippi. It was dark and cold by the time I got to Mississippi and I took the van for a short test drive. Too short. I know better than to do that but it was cold and I liked the car and I was ready to get home. You buy a 30 year old car, you buy it’s problems. But I thought my honeymoon with my first kei van would be a little bit longer than “zero days.”


    On Saturday I took it off of the trailer and started driving it around and within 5 minutes I noticed that at high rpm’s in third it would lose power. Not completely, it would just throttle down significantly. All of a sudden it made sense why the dealer, who was driving the car for all but a very short amount of time, had so much trouble “finding the gears”. And I realized that when I did my test drive I was shifting well before redline. Had I revved up each gear a bit more I would have experienced the drop in power.

    I drive the van around a bit more yesterday and realized that this loss of power happens in 2, 3, 4, and 5 but only when the accelerator is pressed down all the way down.


    If you hold back just a tiny little bit from pressing the gas down all the way it will rev up to redline or near redline in each gear and you can shift normally. But when you press the gas down past a certain point it throttles back. It feels like when you drive a golf cart with a governor on it.

    I know fuel filters can get clogged, especially when they are run down to empty or near empty, but the fact that I can make it happen or keep it from happening makes me think it isn’t a fuel filter issue, right? If it was gunk in the filter then the loss of power would be constant or intermittent and not something that I can make happen or keep from happening. Right?

    But this is a a total guess and I’m hoping someone can suggest what the problem might be and how I might go about fixing it.

    Thanks!!

    You should post in the Honda Acty section. More folks there with Honda experience may know something.
