hello every one im a first time user here so sorry if i make a mistake. I have a 1989 jeep YJ 2.5 singel port in jection,when i start it up the idal is very low but pics up as it worms up then it idels about 900 to 1200 rpm all so under excelaration it fells like runs out of power then i have to back off the throtel to get it to pic up speed. I am at a loss i hope so one has an idea <img src="/forums/images/graemlins/scared.gif" alt="" />
