What up! im new to this forum, I just bearly signed up. I drive a 91 240SX with the KA, its a rare one cuz it has the hicas and abs, but anyways i completely rebuilt the motor. I had the block bored, crank polished, new pistons, rings, head rebuilt and resurfaced. I removed the egr valve, removed the swirl valves in the intake. When it comes to the KA, I pretty much know it like the back of my hand. By reading the problem you have, it sounds to me like the disributor might be off a couple of teeth. I had the same exact problem the first time i fired my KA. I had trouble starting it, finally i got it started but it idled really rough and if i gave it gas, it wanted to die out. I couldn't get it to rev higher than 1500rpms. I then figured that its either i didnt align my chains up right or my distributor was off. So i did the easiest thing and removed the 2 bolts that hold down the distributor so i could get more timing adjustment. i rotated my dist and it started idling a lot better, so i just set my crank to tdc and set the dist cap pointing directly to my #1 cyl, i kept messing with it, if it still ran rough i removed the dist and moved back a tooth or up one tooth till i finally got running perfect!! I was jumping up in the air on how happy i was. This all happened over 2 years ago. My baby girl has been running great ever since. I have about 25K on this motor now and have not had any serious problems with it. I have had one problem but thats a story for some other day. Sorry for all the reading!!
