I ended up getting the codes cleared with a good maf, car is running good - my only concern now is that the car idle's around 800 rpm, and my afr's at idle bounce between 15.0/afr and 15.5/afr... which seems lean to me. With rev the afr's do what they should and are between 12.0afr and 14.0afr...

I'll do that. Also, on the maf plug - I have a 5 pin sc400 maf, the 3 middle pins on the plug have 5 volts with switched ignition, pin 1 and 5 are ground. Does that sound right? Looking at the diagrams it looks right..

Yep, there's power at the maf. Also, the idle air valve plug has constant power to the correct pin whether the engine is running or not - as long as the key is on for switched ignition (ecu on). I've also noticed that trying to adjust my idle with the tps, if I adjust it too far clockwise the...

Oh, also the breather under the throttle body is hooked upto the throttle body like stock. Is that right?

Ecu is a new rebuilt unit from a repairer a Lexus that has been fixing their ecu's for years that I know. Engine idles up when cold but I had to adjust the throttle screw on the ecu down a ways to get it to idle around 700 / 650. Won't idle with just a turnof the key, I have to hold the...

Also, I have the #30 sc400 ecu, the 40p 40p 40p oone, if that makes any difference.

Hmm, well the maf is the one that came with the same car / engine / ecu I got as a whole so it has to be right. The engine was originally running in my friend's factory sc400 so that can't be it. I swapped the maf, but I'm still getting code 24 / 31, and now the motor is running SUPER rich 10.0...

Hey guys, I recently did a 1uzfe swap into my s13. The motor is fully rebuilt with arp hardware, acl bearings and oem internals for extreme longevity and mild boost in the near future. I've put about 20 miles on the motor so far, but have a few annoying issues that are effecting drivability...

Hey guys, I'm curious if anyone has order parts from Lextreme recently. About a week ago I ordered a set of ARP Main bolts, ARP rod bolts, and ACL bearings, totaling close to $800. I haven't heard a word from lextreme since placing my order so I have no idea if they've been shipped...
