  • JDM H22A P0F Problem

    Hello Guys,

    First and foremost, I am new to this forum and I am in no way a qualify mechanic. Just bought an 97 Honda Accord, H22A black top with JDM P0F ECU. I'm having some issue as per below list:

    1. I start my car, some times it runs fine, and some times it will idle rough and dies out. *Suspected IACV, so I had cleaned and tighten the spring, yet problem still remains

    2. When I drive the car for some time, the car will suddenly loses power / hesitate during acceleration some times the car will even feels like fuel starvation and I cannot accelerate further, CEL will show up during the incident happened, once I restart the car the CEL will go away, it will then pops up again whenever I drive it for some time.

    I really hope someone here could help me out on this.

    Hi Rand-

    It might be better if you post to a honda type forum. This forum has very few active members and we are all building K1 Attack kit cars. We aren't here to diagnose random engine issues for a Honda Accord. Good luck to you-

        Try to check fuel injectors. When the car is cold, it goes to another mode and may goes better for a while. We had a similar problem with H22 engine in K-1. It was hard to find a problem, because the car was fine sometimes.

          Based on the symptoms you described, it seems that your Honda Accord is experiencing some issues related to fuel delivery or ignition. Regarding your first issue, a rough idle and stalling could be caused by several factors, including a malfunctioning Idle Air Control Valve (IACV), a dirty throttle body, or a vacuum leak. This can be a serious problem and car repairs will cost too much. I would advise you to buy a new car, on you can find amazing cars in perfect condition.
