i just swaped a s14 black top into my s13 chassi and my idle is all over the place but gets way worse when my cars warm ive checked every sensor and tryed 2 ingnitors, plugs contuine to get carbon fouled i think its my coil packs , its driving me crazy im going to take my coil packs in to get tested and if they are fine i dont know where to go from their . ---

idle surge? could be anything from bad thermostat to your idle air control valve ---

Test your coilpacks, they may not be putting enough power out. Also, what kind of gap are you running on your plugs? Usually 0.8mm will help with fouling. Just a thought. ---

Also, what kind of gap are you running on your plugs? Usually 0.8mm will help with fouling. Just a thought. yah im not sure how to test the coil packs for how much their putting out , gap is at .035inch brand new plugs but the idle problem is fixed for now i adjusted my cam sensor and adjusted my idle air control valve but its still burning threw gas like crazy and smoking a bit im thinking its my fuel pressure regulator but have no way to test it … any ideas on what else it could be ? thiers so much gas beging pushed into the cylinders its getting into my oil a little bit. ---

Usually you need to test the resistance of your packs, my old Skyline’s packs were around 0.7 ohms which is pretty close to factory spec. Also what size injectors are you running? If they are bigger than stock, that would explain the richness. Do you have an adjustable fuel regulator? If so, try lessening some of the pressure to see if that helps. ---

the one thing about coilpacks is, the resistance may be fine (should be just over 1 ohm) but if there is even the tiniest hairline crack in them (check under the rubber too) they will crap out. you can use electrical tape to wrap them if they are cracked, but imo that’s not a permanent solution. ---

so if my coil packs resistance is 1.5 on all of them good or bad ? ---
