Running On 5

[sure33]

Recently purchased an r33 and last week it dropped to 5 cylinders mid drive

Have ruled out anything spark related

Basically narrowed it down to head gasket or an injector

A compression test revealed cylinder 2 had rapidly dropped in compression but the mis fire is coming from cylinder 3

upon an oil test on the cylinder its compression raised back up indicating a faulty injector

Just wondering if anyone has experienced a similar problem and was it the injector or head gasket

any input welcomed
