hey everyone.. i know i havent been on in a loong time just been quit busy with the warm weather and shows.. but i have a problem that is baffling me to all end. as some know i have an h22a in my hatch.. now.. when the car warms up.. i get this suttering and its constant.. basically jerks the whole car and pushes and pull's when u drive it. now.. the fuel pump turns on when the key is turned over.. starts up just fine and idles about where its set on the car which is around 900-1100rpms, the fuel filter is brand new.. im seriously out of ideas and not sure what to look for.. if any help in the direction i need to look it would be much appreciated.

I had a hesitation issue, turned out to be my fuel pump. I was only running 32psi of full pressure with vacuum when it should've been around 42psi Replaced the pump with a Walbro 255, problem solved.

My pump always primed when I rolled the ignition on, just was old.

I've heard of other things causing a similar problem.

However this might not help your situation. Hope this helps, Good Luck.

Buy a fuel pressure gauge and see where it is running.
