okay so i posted about having just crappy performance and my exhuast smelling of raw fuel someone told me the FPR had finallly gone out...read up yeah made alot of sense.
okay so i put on the new FPR

Idle is much smoother when cold (it used to shake alot) and the exhuast smells....well like exhuast should no raw gasoline smells.

BUT
still no acceleration or power under 4000RPMs and sheesh its been really sucking on the 1.45 gas.
now i am replacing the fuel filter friday ( its my final exams week....sorry volvo got to hit the books)
and i noticed today a crack in the pipe connecting the exhaust manifold to the CAT.
would this make sense as to why the engine dosent accelerate and sucking the gas?

oh and i checked the wiring connecting my coil packs above the spark plugs about a month and half ago, they are by no mean new (getting them replaced as soon as i get my books sold back at 1/90th what i bought them) but they havent rotted completly away.

hey thanks for all the help! haha had there been no internet i wouldnt have even bothered with anything but american cars.
