I recently bought a 300zx 1991 N/A.
It was running perfectly for about 3-4 months after i bought it then we had some pretty bad snow and it sat for a day and a half and everything started happening.
Coolant leaks (fixed) horrible idle, i need to keep my foot on the gas when stopped or it will shut off, its lost so much power, and i did a compression test and they were all over the place (150,150,140, then 90,100,&50) i hope its not a head gasket but all signs point towards it.
