Yes 14.7 is the ideal mixture. But going thru some turbo forums they mention that engines with turbos should run a little richer than naturally aspirated engines. 12.8 to 13.7. Correct me if i wrong. My experience with turbos is very limited. Yes when i back off the accelerator it does go to 27.0 + on AFR Oh FYI, I have the AFR plug in into a whole different oxygen sensor after the cat on the exhaust.

Update. So I drove it the car for a bit and it seems that the rich smell has gone away and AFR monitor is taking the readings from the ecu adjustments. So far its stable at 12.1 on AFR.

Ok something is not right. So I finally was able to replace the O2 sensor and now my fuel mixture is way higher and Im getting the ecu led flashing. But not in a way to get a code. But when i disconnect the new O2 sensor the light goes off. Any thoughts or suggestions. Or should that be normal blinking operation.

Theres no fuel leak and holds vacuum with the gun. Also change the vac hose that goes to FPR. I will try to change the O2 sensor this weekend by trying to remove the heat shields.

Heres the oxygen sensor where i can't fit the socket due to the heatshield surrounding the sensor.

By just testing the the fuel pressure itself would tell me that the regulator is working properly right?

I have also replace the vacuum lines, even tho the original braided ones were pretty cool. Inlet pipe still looks flexible and dont see any cracks. I tested every injector when I removed them to change out the fuel line. No leaks on the fuel pressure regulator. It holds vacuum. I have not tested the fuel pressure yet. Im running an after market fuel pump since a original one cant be found anymore. Its rated for the recommended lbs that that system requires.

Oil level has been on the spot. Just getting the oil pump small leak that I read about here in the forums. I dont see any smoke coming out from the tailpipe. No black soot on the tailpipe at all. Just the rich fuel smell that comes and goes.

That would be helpful if you can. So far i dont really see a issue with turbo.

Yeah I've replaced every piece of rubber fuel line all the way to the injectors. The injectors were removed and clean all of them. I did purchased a 22mm hex slim neck socket for the O2 sensor. But its a small area to get to the sensor cause the heat shields that make it difficult to fit the socket. I will remove the heat shields this weekend lets see if i could get to it.

So my wagon has fail smog twice so far. I have replace plugs, fuel filter, air filter, cap & rotor, pcv, checked fuel pressure regulator. Except O2 sensor. O2 sensor looks like it had been replace before. I notice that when O2 sensor is unplug it runs a little leaner and when i plug it in it starts to get in the rich side. I having a problem trying to reach the O2 sensor with the standard O2 socket. The heat shields on the turbo and cat make it difficult. The service manual calls out for a special socket for the sensor which i assume it doesnt exist anymore. Any suggestions...

Thats the only thing i havent test yet. I dreading it, cause if thats the problem im going to have a difficult time to find the replacement fuel presure regulator. Also having trouble removing the oxygen sensor. I need a thin wall socket just to get in between the heat shields.

Thats the only thing I haven't done. I dread it cause if thats the issue. Im going to a difficult time to find a replacement. Also having a difficult time trying to remove the oxygen sensor. I need to get a thin wall socket.

Thanks to all. I'm finding out little by little why it was parked for ten years. Its running rich and has fail smog twice. So far I have replace everything but the oxygen sensor. I will start a thread on the on the Old Gen forum to see who could give some suggestions.

Here from Chino California introducing my new 1984 GL Turbo Wagon. I believe im the second owner after all the hassles I've been thru with DMV. I found the car on craigslist after just browsing thru the ad's, It was a barn find. The guy I got it from had it parked over ten years. What got me interested was the low mileage. I has 95236 original miles on the odemeter. The car is pretty much complete. Just a dent on the driver side door. What sold me was that it came with the complete factory service manual. And the car manual with the maintenance book with all the services done at its proper mileage.
