okay Zilvia i just swapped my s13 convertible with an rb20det its completely stock aside from the grand national coil pack and rb25turbo. I got it started and it runs super rich and is in limp mode, so i checked the ecu and its throwing code 55 and i thought it has to be the maf(new one is almost here) but looking into it further if i unplug the mafs and the tps shouldn't it run a lot different. could there be a wiring issue to cause this or possibly a bad ecu? i have been looking shit up for a little over a week
