Enthalpy ECU w/ 550's Z32 MAF

I finally got It started, it ended up being the battery and a MAF grounding issue.

However when started the rpm's go up to about and then start fluctuating between 1500 and 2000. After about a minute the rpms begin descending, getting to around 600-700. The engine then struggles at that point sometimes shooting up to 2000 rpms before eventually descending and stalling out. Total time is anywhere between 3-5 minutes.

Any ideas?

umm, are you keeping it running with giving it throttle? jookmasta had a simalar problem with the car not ideling at all, his solution was a blown off IC coupler. check your IC piping maybe.

Make sure your MAF wiring is right. The 12 volt and 5 volt reference wires not switched.
