Off of those codes. we went into the st205 repair manual. And did every step they say with checking volts and everything.. We checked the coolant temp sensor and the map sensor. And both came out fine for voltage and also checked the e1 and the +b on the ecu. them came out correct also. So i'm really running out of things that could be wrong with my car. Everytime i start it. it goes to 2oo rpm and bounces. Also runs rough and rich. can't ever get it to clean back out.

I just had the map sensor code and it made my car super rich too. Did u test the sensor output to see what ur base voltage is without car running... And then test it when at idle. Mine ended up being bad

[celiracer]

I believe we did. and weird thing is in my 95 gt that is my daily driver. that map sensor in there is same part number. and looks identical to the one i got for my swap.. were running out of ideas. and it's stressin me out.

[celiracer]

Cleared codes. and let it run again. Now only codes i am getting are 42 and 47. But still can't get it to idle right. It just idles rough. And goes from 1k rpm and goes down to 200rpm all by itself and burns black smoke like crazy.. Anyone know of any other ideas? starting to run out of them lol.

[DG_Performance]

Sounds like u got the wrong map sensor with ur swap A third gen map sensor should have a purple label on top and there is no way a regular gt map sensor is the same.

[celiracer]

Well if i had wrong map sensor would it still run and not throw a code?? and it's the same part number that i got from lithia toyota.. Whats the part number for the 3sgte map sensor? Maybe that is my biggest problem all along and i would like to fix it lol.. also what is code 47? I can't find that code anywhere on the repair manual..
The map sensor i got with my swap is 89420-20300.. and looking off other people with part numbers its supposed to be 89420-20310? Or manny's sticky with part numbers is 89420-17050 Which one is it?

A map sensor that is wrong will let the car run but run crappy. So yes it could be not letting the ecu throw u the code cause it sees a working map sensor and don't know that it is the wrong one. U can use the 310 or the 050 but not the one u have!

[celiracer]

ya i figured that' lol. thanks man. finally found my problem... hopefully get one here this coming week. been driving me nuts. lol.

[DG_Performance]

I have a connection I can get u a brand new 3rd gen sensor for 290 shipped. If u need one let me know

[celiracer]

thanks man. should have one mon or tues. hopefully get her running this week so i can take her out lol as long as i got all the gremlins worked out of her lol.

Here's the part number for a ST205 MAP sensor :

89420‑20310

Ya. thanks man. I was supposed to have one next day aired and have it mon or today. But still haven't seen it yet. So i guess we'll see when i get it..

[celiracer]

well good news. got map sensor this a.m. plugged her in and she started right up. messed with idle. changed my plugs and got radiator fluid all full. and changed the oil. started it again. and took it for a test drive. make sure couplers were gonna hold. hit 5 pounds everything held ok.. took it home put hood and bumper on. then i started it when it cooled down. it idle at 4 hundred and sputtered. sometimes die. then once warmed up idle is at 9 hundred and fine sputters every once in while then. with ac on and stopped it'll idle an eventually die but when driving around with it. it runs fine. any ideas? just mess with idle more? thanks in advance.

sound like u got the wrong spark plugs in there... i just changed mine the other day did the same thing took them out put my ngk's back in and is running fine now

[celiracer]

ya. I got the oe ngks in there now.. that's why i wasn't thinking that was the problem..

[brenton1919]

ya. I got the oe ngks in there now.. that's why i wasn't thinking that was the problem..

is it flooding did u make sure all your injectors are working ?

[celiracer]

oh no injectors have been checked. there good. not flooding as i drove it 75 miles last night.. when on highway i opened it up in 2nd hits about 15 lbs but while it's there it bounces from that to 14 till i let off.. only time it sputters is when i'm stopped and at idle don't do it while i'm driving it'

[DG_Performance]

Make sure the middle size vac tube from under the tb(the iac hose) is breathing easy. And the vac switching valve is not clogged up with gunk too. Take of the tb and clean out the port for the iac with some carb cleaner. Idle should be nice and smooth after that. Unless u got a random vac leak hiding somewhere.

[celiracer]

Yea we cleaned that all out when engine was getting reassembled. And the IAC has a filter on it. So it should be breathing pretty good..
