I'm working on an eg with an H22a. The car idles perfect. But when I rev it an hold a steady RPM the car bogs down and then revs back up. When driving the car it will buck and then pick back up. On my datalog it shows the injector duty going down to zero for the amount of time with no power. I have already checked the fuel pump wih a voltmeter to make sure it wasn't cutting out any ideas? Thanks for any help. IAm guessing it is an electrical isue if any one could point in the right direction that would be great.

 

I really need some help I want to get this car out on the street.

 

Are you using the stock H22A injectors, and if so are you using a resistor box?
