So I posted a while ago about my 87 N/A supra having problems where I could hit pedal to the metal and the car would just bog down and had poor acceleration. It kinda picks up around 4800 rpms.

Well, I've been working and working on it and it's still doing it so I hope someone can give me some advice based on what I've already done.

So far I've checked and adjusted the timing, installed new ignition parts (new cap and rotor, new plugs, new wires and new ignition coil), tested and adjusted the TPS, tested the EGR and even tried blocking it off completely, compression tested the motor, taken the intake completely off and inspected it, and the car also has a brand new cat converter and o2 sensor and passed smog with flying colors.

How frustrating, anyone have any ideas?

Well it's got a new MAF now and same problem. The cat is new but the pre-cat isnt so maybe that one is all plugged up.
I'm gonna replace the fuel filter this weekend :( ugh
