On my h22a swap on my 92 Si, I have put about 700 miles on it and have worked out most of the major problems. Most of the time, it pulls hard, however ever once in a while, when I go to accelerate it stubles and feels like there is zero power but with very small spikes in power.

My main realy was bad, however, I resoldered where a solder joint was cracked. Timing has been set correctly.

I am thinking that it may be something with fuel. has anyone else had a problem like this.

Check your fuel system is clean, ie injectors, fuel filter etc

might help?

mums old accord did that a while ago, and i think thats what fixed it from memory.

 

I have this same exact problem. Like in the morning it will be fine for a few miles, and then it will be all wierd. The car gets louder but i feel as if i am not even acc. I thought i might have a vacume leak. LMK how it goes and i will let you know if i find anyhting out on mine.

 

I am going to change out the fuel filter this weekend and then run a thing a fuel system cleaner (although I am still a spectic on that ****) and we will see what happens.
