if the car's been sitting for that long, you may have bad fuel. have you done a compression check on the motor? last time I experienced popping it was due to bad fuel and 2 dead cylinders. That's what happened on Gino's B13...the first motor he bought at Soken was bad and there was about 2 or 3 gallons of bad gas in the tank. We tried filling the tank without taking the bad gas out and that didn't work. We had to syphon(sp?) all the gas out and put in fresh gas.
