Tried Starting my CA, but won't stay running

[Sil40sK]

Hey guys, I got my CA in and have everything wired up. I tried firing it up last night and it turns over and starts then stays running for about 15 seconds at around 1800-2000rpm and then drops down to around 1100 then tries to recover but dies off. I tried it again and whenever I put any amount of pressure on the throttle pedal the motor dies. I checked all the wiring with the write up on HeavyThrottle and tightened down my ECU plug but the problem is still not fixed. I'm running a stock CA18DET in a 1993 240SX hatch with a KA24E maf sensor on a stock airbox, with an hks wastegate actuator and ssautochrome (i know it sucks) manifold. Any help would be greatly appriciated. Thanks.

Sounds like a vac/boost leak. Check all of your connections and vaccuum hoses.

vac leak, crappy gas is also a possibility if it has sat for a while (like mine had, it would do the same thing till I changed the spark plugs and added 5 gallons of fresh 93 octane. )
