the compression is 160,140,150,130. I thought maybe a blown head gasket, but the compression test and no water in the oil or oil streaks in the radiator
water I think rule that out. when I did the compression test there seem to be gas spraying out of the cylinders and I checked the spark plugs again when I had them all out, its not a big blue spark, but white/gold/blue spark. they seemed in rhythm. There was sporadic air pressure coming out of the exhaust
pipe, but I don't know what a good amount is, in case it is the cat. converter.
It seems like if it wasn't getting enough air flow, or if a computer malfunction (if that is possible on a 1993 Toyota tercel).
When it had been sluggish, (sometimes not getting over 35 when trying to speed), I did put some good fuel injector cleaner in the gas. two days later it just died while driving.
I changed the spark plugs, rotor, cap, and wires.
