1995 eagle talon tsi fwd automatic:

Hey Heres the scoop i pulled over to put gas, i didnt put 93 octane i put 89 i believe, the one right below 93...so w.e i was driving and somewhere along the way i noticed a power loss, then when i was driving down the highwayi noticed my RPM wasnt rising above 2800....and when i tried to accel i heard a sound that sounded something like a like a food processor, so im like wtf right....so i keep goin slowly....till i get to my house 2 min later...i pull over i notice i had a leak in my air intake pipe...so i tightened the screw to tighten the clamp....so i go start the car and go around the block....this time it squeaked when it got to 3000rpm...so wtf...i pull over to park and i here my engine as if something is tapping inside as if it were a piston/valve...
P.s: running stock boost w/tune....

Necesito Logs.

Have you put 89 octane in before with no problems? What boost are you running and shit?

He said he is running stock boost. Your probably experiencing knock because you didn't get high enough octane gas. Correct me if i'm wrong. For the intake thing, I don't know.

Is this tapping noise coming from directly under the valve cover? (lifter tick)
Does it sound like a bunch of marbles moving around in a can? (rod knock)
I would do a compression and boost leak test to be on the safe side. Changing your filter and plugs and oil wont hurt you either.

stock boost...i have a feelin it might be one of my piston rings and the problem got worse because 2 weeks ago i had a shitty mbc controller that had me running 28PSi on a T-25 for about and hr till i realized....and since then i noticed a very little power loss...then last night it just all got fucked up..

Well stop driving it and perform a compression test.

I don't think it's possible to run the T25 at 28psi!

The labor you are paying the mechanic can probably buy you 5 compression testers.:banana:

I think it's mechanical, I would open the valve cover and make sure nothing is loose, check the timing marks then perform a compression test.

No, unless you over tighten the bolts and crushed the gasket last time.
