3sgte vacuum diagrams

[wags70ss]

I am looking for vacuum diagrams for a '91 3sgte engine. I need them all to figure out where all the hoses go. Any body got em? Thanks!

I am also looking for a t-stat housing for the same engine. The machine shop lost mine . Any help there?

I'm at work right now. Bit if someone else doesn't get a diagram to you 1st, i will post one for you when i get home from work(between 10-10:30CST).
As far as the T-Stat housing, PM MR2Guru. He's parting out. tell him I sent you. I bought a distributor from him. He's honest

Cool Thanks. I need one for a '91, I guess the '92 & up is different. Also, I have a j-spec engine (no EGR) so that might make a difference too. I also eliminated the TVIS, & I need to plug the correct ports.

That is a '91. TVIS line routing is the same.

Got the vacuum hoses connected, Thanks! Sarted it up for the first time 2 days ago!

Got 3 other questions.

1. How do I probe the diagnostic link to get codes, & where do I find code definitions.

2. The original downpipe had what I thought was a second O2 sensor at the bottom of the catyletic converter. I called the parts store & they said it only has one O2 sensor. I removed it from the original downpipe & it looks to be a probe of some sort. It has 2 wires, black & white. Any body know what it is? Can I bypass it some way or do I have to use it in the new downpipe? I was thinking of crimping the 2 wires together to see if that would help, but I dont know if it will.

3. Anybody know a good tuner in the Kansas City area that knows computer systems on the MR2? I replaced my ECU with a Blitz ECU & I need to have it checked out to see how it is working.

Go to the diagnostic box on the latch side of the engine bay. use a paperclip and cross connect Te and TE1. Then, turn ignition to on position -but do not start car-and count the CEL flashes. There will be 1 set, pause, then another set. Ex: 5 flashes= 5 then pause, 2 flashes=2 ... code 52
Let me know what you find and I will look it up for you..
Is your DP stock? There is only one sensor on top of the turbo elbow-O2 sensor. If there's another it may be for some type of engine management from before.
Can't help you with the 3rd one..Google it
