Still working on misfire
Have trouble finding problem. Codes 1300, 300, 301, 305, 306, 308.
New bosch sensor, new bosch plugs, new STI wires. Runs way to rich. Plugs are not burning gas, checked plugs with misfire, they are wet with gas. Gray smoke out the exhuast, has strong gas smell. Decided to have injectors cleaned, no change. Checked fuel pressure. Key in position 2 (car not running ) no pressure. Start car 50 psi, turn key off no pressure. Not sure what to check next, thinking of changing plugs or at the very least swap them around and see if i can move the misfire. Not sure why pressure drops as soon as key is turned off. Any thoughts, thanks

I miss read my meter, coils check to be good. Swapped them to see if it would make a difference, no change. Still have same codes.
301,305,306,308,1300,300. No more fault codes, no sensors, nothing.
I will make a compression test as soon as i can put my hands on a tester, not sure what to check after that. Need help, thanks.
