Friends car, I will give as much detail as I can.

03 Spectra. 1.8 Manual
Few days ago, acceleration got worse and worse.
Yesterday could shift all the way to 70mph, however took forever to do it.
No tach so I'm not sure what the RPMs are. Seems to stick around 3k maybe.
Today, car won't accelerate past 25mph.
No odd noises, engine seems strong. No hesitating or missing. RPMs are smooth and quick in neutral.
RPMs are smooth but slow in gears.
Only noise is rattling catalytic converter.
Exhaust is clean, no smoke.
Engine oil and coolant are clean, no contamination (no blown head).
Haven't been able to check the trans gear oil at this point.

Any ideas? Please and thank you.
