I was plagued with an intermittent misfire for the past 3 months.the cars power is great.The problem have been fighting with is a stumble or misfire off idle when accelerating from a stopped position . I had a very strong feeling it was fuel. I had emptied the tank,cleaned it.Changed the fuel pump,changed the injectors,changed 2 fuel filters,cleaned the injectors,replaced tps,ego,isc,coilpack,leads,plugs ,checked cat,checked fuel pressures while driving.
It was getting very dangerous.Tonight I turned the pressures right up on my big injectors and voila not only is the hesitation gone but throttle response is alot better!!Just like the standard injectors!!

Standard injectors were at 39 psi. My bigger ones at 45 psi.This was not enough to keep the problem away.Now at 55 it seems good.
