Rb25 Rich at Startup and Misfires at High Rpm.

Heres a list of what the car does.

1. Acts hard to start and idles rich enough to smell gas heavily.

2. Idle hunts a little bit untill holding revs above 1200rpm for a couple seconds. My guess is a cause of the extra fuel.

3. Free revs perfect to redline but misses heavily under boost and wont rev higher than 5000-5500rpm.

Fuel pressure is set to 45psi. Idle is set to 750-800rpm. All the plugs are a tannish/white color.

set tps to .45v at idle, set timing, mess with idle control valve, have a beer.

Ill check the TPS. I know timing is good at 15*.

I changed plugs from BKR7EIX to BCPR6ES-11 and it started missing worse. Both gapped at .030". Seeing 2 good sets of plugs do it, im thinking some coil packs are bad.

Checked resistance on the coil packs. There sopposed to be within .6-.9 Ohms.1) .62) .53) .64) .65) .56) .6Now being the resistance is below the OEM minimum, does that mean they are becoming weak?

Also i tried getting a voltage reading of the TPS and no matter what i tried, i couldnt get a reading. I followed the FSM and no matter what i did, the number would start at .6 and slowly drop to .1. I tried to move the TPS and you could hear a change in idle but no change in the voltage. I just set it back to stock since the car drove like that. I did check the resistance and it was reading 1.08 or something. OEM is sopposed to be 1.3 i think.

Try a new TPS, they are cheap and I've seen a ton of these cars have bad TPS's.... mine comes to mind lol might be mafs related too
