so ive had my swap done now for about 2 months into s13(bought from a friend was running and driving with no problems). put it in got it running, ran like crap knock sensor was unplugget and I put new plugs in, fixed ran awesome. the biggest plug gap I can run is .026 or it cuts out maybe that normal but that seems kinda small to me coming from sr to 1j and now rb(should have stuck the 1j). that was an sc300 though. anyways my car kept going into limp mode like I had a bad maf and it would fix itself on its own, it never does that anymore though. now after it warms up it has vary noticeable power loss and it even sounds different, like its pulling timing or something. things I have done was throwing code 13 got a new coolant temp sensor didn't change checked voltage at ecu for knock sensors they were both 2.5v at idle set tps and made sure it was correct when set while wot and closed boost leaked checked multiple times and its solid haven't messed with bov still recirc tried 2 different fpr's and new z32 fuel filter put extra grounds from block to chassi and an extra ground on coil pack harness checked voltage at fuel pump 12 volts when I put the motor in the timing was set at 20 degrees according to how you look at it rb's its kinda weird depending on the angle you look at while timing it. it had been that way for a few years with no problems im timing by putting my timing light on the white wire at number 1 coil with the timing light hooked up to a jump box for power because my battery is in the trunk. maybe that's all no good and need to make a wire from the coil to the spark plug and use that to time it? now after about a week it throws coolant temp code again, so I ohm the wiring between sensor and ecu and I doesn't say offline but it reeds o.o ohms. I check the ground and its 3. something. info about the swap s1 rb25 mostly stock I think its an older wiring specialties harness but its a little old now hks actuator set to 9 psi n1 thermostat walbro pulled from my friends running s13 and about 3 weeks later running in mine pumped all old gas out of my shell and put new premium in cx racing front mount 3 inch dp and exhaust I don't mean to ramble on to run so good and strong sounds good while its warming up, and I don't mean dead cold and romp on it I wait till needle starts to rise on temp and pulls hard all the way to redline, then temp gets halfway up and gets slower and slower till it sounds way different and feels like has no boost just a na motor, still drives smooth though doesn't cut out and super rich. I don't have a wideband but it uses tons of fuel and backfires a little usually when I take my foot off the gas and start coasting. ive tried everything I can think of and before I rewire my coolant temp sensor to the ecu I figured I would ask. ive b
