ok, last night we installed my new toys, a blitz SBC-Id and a blitz powermeter-ID, ive had a bad surging problmen at crusie for a while, i didnt have boost gauge with vacumn readings so i didnt know till last night that the surging always happens around, -2 and 2psi, i probably have a boost/vacumn leak, but tonight it started idling funny again it would bounce from 850 down ro 100rpm and should stall out, but it wont it will start back up and bounce back up and down to stall again but it wont the battery light will come on and it will bounce back up again, then its sputtery and surgy when yuo try to drive! when its trying to stall the motor isnt bucking like it would normaly its very very smooth and quiet it seems to be still purring but its just wanting to shut off but wont.
im starting to think either my MAF is dirty again already. or im having a fueling problemn, my pump has been unsually loud lately and now its not, kinda comes and goes, im using a walbro 255 highpressure, im smoking again black smoke under boost, so that should mean im over fueling.
it just doesnt feel like a air leak this time. more like lacking and then having too much fuel. i still havnt found a fuel pressure gauge to use to check it, the ricer shop here wants 35$ to check it for me. any suggestions?
