running poorly

TII engine s4

So yesterday the car was running flawlessly and today on the way in to school it was just running like crap everywhere in the rpm range.

I can usually make 8-9 pounds of boost but could only make 5 max. Also when cruising I am usually at 10-12 inches of vacuum but am now at 6.

I suspect a decent boost leak somewhere but I couldn't find any so before I go pulling the uim looking for problems I am open to other suggestions.

Yeah im thinking a cracked side seal or flatten sping? Just throwing it out there, not like it hasnt happen before. Either way a compression test will give you a good understanding.

Wow that sucks. Screw an LS1 though, I would just get another car if you're sick of it.

For now Im going to drive it until I fix the clutch in my truck, then its going away early for the winter.

I am not sick of the car and I could never get rid of it, I just cant afford to keep replacing these engines.

Get a daily driver Best purchase I made for my FC is... my Honduh Civic Si. It gets me to work, so I can earn a paycheck and to throw money at the FC. It also allows me to drive to places to buy some parts. Felixisgod29x knows
