I’ve posted in other forums and haven’t got any answers even though everyone’s tried to help. Hope you guys can help me out.    I had a mostly stock 1995 gt and had a fox edelbrock manifold laying around so decided to install it. Put a bigger fuel pump and 24 lb injectors. Fairly simple stuff. Spliced the tps wires correctly by color and set it to .98 drilled a hole in the new cold air intake for the air temp. And new fox throttle cable. It turns on and the idle will surge a little Im thinking maybe a vacuum leak somewhere but it’ll start running funny then die and won’t turn on after it warms up. Timing is set to 12 degrees. It gives me a few codes Koeo 117512 (not sure if I get this because I keep the battery disconnected) Koer 998 117I think 998 is the problem. It says it’s operating in failure mode. I have no idea how to fix it or where to start. Thanks in advance.</blockquote>
