Well as many of you know i have the st185 swap and ever since the accident, sphinx and i have noticed that my car isnt running up to par... I honestly think that his is faster than mine, i know it depends on the driver also, but i mean on top of him being a better driver i still feel his car is running better. I have driven IN his car and actually driven it so i can tell. We have about the same mods yet his is faster. Well one of the things that we noticed was that my injectors are working pretty hard/high. When the car is idling or warming up, my AVC-R reads that they are working at 93% or so, but when i start driving it goes down to about 81%. Yet when i drive sphinx's car or even when Im in it it idles at about 84% then when its being driven it only goes down to about 81% (sphinx can verify the #'s).
Well sphinx has been wondering what could be the cause of this problem but he cant seem to put 2 and 2 together. So i am seeking the help from you guys here on the boards to solve this problem I am having.

Thanx in advance,

Almost boosting,
David

The "Jerk back and forth" should be "lack of fuel". The 2 culprits that I can think of are;
1. Dirty Fuel Filter(uneven fuel flow during high rpm or boosting).
2. Your Fuel Pump is weak. Are you still using the stock fuel pump??

1. Sphinx changed that on mine a few months ago, like 3 at the most. So i dont THINK that would be a problem.
2. NO, i dont have the stock fuel pump. If i remember correctly i have the Walbro....something i cant really think about it right now.

So now what other options can i look for?? If i have to ill check the fuel filter again I will. Thats not any hard work.

Almost boosting,
David
