so i had mikey in the car for a listen and he thinks it sounds like bearing (metal on metal). its been making the sound now for over 2000 miles. wouldn't the bearing be shot by now? its also strange that the noise does not occur under 3000rpms and is silenced by boost pressure. i guess the first step could be an oil analysis.

i speculated maybe my shotty solder job on the injectors was actin up, but the car does not stumble or miss. if i had a bad electrical connection with my injector wouldnt it run rough as hell on 3 cylinders? car runs well and makes power.

one thing that was evident is that when i was reproducing the noise, fairly dramatically buy stabbing the throttle to 4k rpms, my IAM fell to 11. this was done in neutral.

on my way home from the sonic meet, i got a flashing cel after some aggresive acceleration. when i checked it today it was my infamous p0000 and the IAM was 15.

got a jdm grill the other day...
