Cograts on your fix, i have a problem that maybe you guys can help me with, when i start my car when its cold, its really hard to start and doesn't want to hold an idle unless i give it some gas, then about 15 seconds later it will hold idle fine. It happens occasionally when warm, but when its cold it does it often, it sometimes doesn't want to crank, but when it does it'll fire sporatically until i give it gas and then it'll setle back down fine. The motor is an RB20det in a usdm S13. Thanks!!

i would check:

airflow meter

fuel pump

spark plugs

in that order.

what does the car idle at, what does it idle on start up? Is it higher when its cold or is it just the same when cold as when warmed up. could be something to do with cold start, but thats just a random response, try and be more specific, what mods have been done to the car???

Sorry to revive this thread - just wanted to give my thanks as I had this exact problem and it's been annoying me for weeks! Went through all the usual bits, AFM, Coilpacks, AAC Valve, CAS, TPS, ECU and it ended up being this Fuel Pump Control Unit being unplugged! No idea how it came out, maybe when the jack was last taken out or somehting..

nevertheless I'm so freaken happy now !!
