PM'd ya batman. I'm starting to fun out of ideas. other than injectors and or my ECU being bad. Hopefully i fiigure it out.

they're not bad IMO.
If tweek did the wiring then IIRC he doesn't use the fp relay, the fp is wired to run at full power all times. Not a bad thing, but not the stock way.

Change the 02 sensor first.
You can use the st185 02 and splice the plug to the 205 one.

post some pics of the engine in the bay. I want to see if you have everything hooked up right (vac lines, ect), it could just be something simple.

Alright. I will take pics of bay and get them up hopefully today.. I order'd a sensor for a 93 all track. But i have to splice it in? And would the 02 sensor really make my car not idle and run rich? I'll have em up shortly

are you using an 02 now ?

A bad 02 would make it run very rich, it determines the a/f ratio.

ya i'm using the o2 it came with. so i guess that could very well be possibly it.. so the 5th gen altrac one i splice the plug off mine into it?

On my car I had to switch to my own stock 02 over the Innovative one that came with it. Also I thought that your stock 02 for the computer should be in the normal spot and you weld in a bung for the Innovative. I ended up doing that. got rid of the one it came with bought a stock one, then bought another stock one for the factory location.

The Innovative is nice and accurate but it really is a PITA

lol ya. it's not the o2 from the wide band that's bad. it's the actual controller that's bad. I can't even calibrate it. but yes i'm running stock 02 from engine. pretty much only thing i didn't replace besides all the sensors. but hopefully that will be the problem. i'm just wanting to know if the 5th gen altrac one works. and if i have to splice in the wires? cause if so i'll be doing that tm.

yes.

We have no idle adjustment screw.

change the 02 and clean out the IAC.

So rechecked fuel pressure and my fuel pressure with the +b and the other bridged and key on.. it reads 42lbs and then when i start the car and keep gas pedal around 800rpms it puts pressure to like 50lbs... My dads wanting to re wire the stock fuel pump in to see if changes anything. But i think thats a bad idea? and would hurt the engine? any info on that?

as said before, pump does not regulate fuel pressure, fuel pressure REGULATOR does that, so if fuel pressure is higher than stock, look at the regulator, not the pump.

Yes i've gotten the regulator out.. Problem is. is trying to find a new one.. lithia toyota don't carry them.

Got regulator out. When took it out we found some problems with it. So i'm looking for a aftermarket regulator. or someone selling a stock one for the 3rd gen 3s. lol

call dr tweak he will get u one. and u can always find one on ebay just go to ebay uk

I have one. I'll pm you.

Are u not getting a check engine light? Did u bother to check for any codes?

DG. No check engine light was on.. and no codes were going off.. When we unplugged the IAC the check engine light came on. But then shut off when we plugged it back in. So we know the light works lol.. But we figured it out.. when we took regulator out it had fuel coming out of the vacuum port. So thats my rich/idle problem. and also had the iac line capped off so that will prob fix my idle problem also lol.. Hopefully get my part today or tm and get her running lol.

Fuel pressure regulator came in today.. Got it put on and put a filter on my IAC line.. Started her up. And she'll idle finally lol.. Idle is at 200 RPMs tho. And at that RPM i'm at 38 or 39lbs of fuel pressure.. That seem right? or still to high? My cars still smoking garage out in couple min. And seems to still smell gassy.. So wondering if there is somthing else screwed up. or if it's about right if we adjust the idle.. thanks in advanced

Well got idle up to about 1k. But while its running it'll run fine at that idle then it'll idle down by itself (while still warmed up) And start blowing smoke. And miss a few times. (with brand new plugs only had car running for twenty min with them) then it'll go back up to 1k rpms and clean itself back out.. and few min later it'll go back down to 8 or 9 hundred rpm start blowing smoke and missing. Then go back to clean 1k idle. does it all the time. Turned motor off. checked plug and there all pitch black already from only running twenty min.. So i'm thinking o2 sensor or a coolant temp sensor is bad or somthing making it do that.. any ideas? thanks getting happy that it atleast idle's now lol.

And after it ran for that twenty min to a half hour the check engine light came on. So gonna prob hook it up to diognostics tm. And check that out.. Maybe will tell me my problem that i have now lol.. We'll see. getting pumped and ready to role this out onto the streets tho lol.

Also i found out. when i rev engine to about 4k and try to go farther. it stops at 4k and goes to like 2500 and starts burning rich again and rpm wont go higher then 4k. I know it seems like i'm having a crap ton of problems with this swap.. wish there was someone around my neck of the woods with this swap to help me out lol.. But it's just me around here lol.

So u are using the old oxygen sensor that came with the swap? If so... Buy a new one on partsgeek for 95 mr2 turbo for like 53 bucks.

its not the oxigen sensor, i had no one on my car for one run and it doesnt do that bad,
the normal rpm is 700, your engine try to get to normal rpm after warm up, i have seen other treahd that ppl cant go more than 4k but i dont know much about it, check the old threat, you should find anwser
