I was getting on the freeway, the car jerked i saw my wideband was jumping around anywhere from 13.2-15.3 really fast. I recently changed my injector resistor pack, coil igniter, as well as a brand new fuel lab fpr. At a stop when i rev(3k rpm) it falls off and dies because its loading up. I changed back the resistor pack and changed back to stock fpr and no difference made. I know my idle speed control is next to being garbage right now, but what would cause it to run super rich like that? In driving conditions i can boost just fine and it runs full rich(10.0). I really dont know where to look for this problem and anything helps really. I tested my bov, maf, closed throttle switch, resistor pack, coil igniter, intake couplings(for leaks).

I'm assuming that the jump your seeing is on a wideband. If you don't have any boost leaks I would check the plug gap and wires. What are you tuning with? I know I have had wire come loose on my safc2 the rpm wire and it will run like hell with the symptoms you have described. Are you getting any cels?

Yes it was my wideband reading. I did boost leak test today and no leaks, i did it with my intake tube as well. All my safc wires are sodered and heatshrinked. My idle speed control is going out is the only thing i can come up with. Its nonexistant to find those anymore. Also no Cel's D;
