94 Del Sol
Factory B16
Stored for winter on a battery tender with 15 or so minutes run time once a month.
It'll start like normal, run and rev up like normal
After about 15min, start to hear an intermittent pop or chirp from tail pipe that slowly increases in frequency. As it steadily increases, car will misfire off idle when you stab the gas, but will rev up. Eventually, this all continues to get worse until it stalls out and won't restart. It did restart after sitting for 2 days, but did the exact same thing over again.
I'll have some time this weekend to try and diag (fuel pressure, spark etc) any ideas where to start?
