I wonder if some one can help 93 wagon 300TE... iS THERE A WAY TO READ the fault codes on car I have that 16 pin black box by the side of the battery buit no switch or LED on this box..... I would appreciate if some familiar with this car can help I need to solve the rough idle
I have tried a few things but wanna see the codes first and I hate to go to the dealer .... you all know they prefer working on new cars..!!!!
Isn't there a button right next to the LED light near the pins? Your supposed to hold it two-three secs. and the light will flash, count'em. Those are the codes.
You need either a SDS diag. coumputer or a magic mushroom with an impulse counter to start. BEST plan B replace connectors on the ends of spark plug wires & DO NOT WASH this engine!!! water collects at the connection to the plug wires. If this does not fix next step check for a bad coil, if this does not fix it , sorry engine wireing is the next step.
I did some work on my wagon Cleaned the intake side manifold / Throtle body, replaced some hoses Spark plugs and stuff I got my idle smooth now,......
When the engine is cold Idle is still rough but above 70 deg C its perfect...
I checked for any spak leaks at night no leaks of faulty connections...I did check resistance across temp sensors it drops from 1600ohms to 500 ohms and the other (for gauge ) drops from 110 to 50 ohms with Engine Temp rising from 40 deg to 80 deg c...
Any suggestions guys... I'd very much appreciate that I know some brilliant guys are out there....
just for your info I do need to put a new Masa Air flow sensor as the one now is broken..... Is MAS going to affect Idle when cold...!!!!

I'm still desperately lookinf gor a way to read codes...
Thanks guys..

you hold the button down for three secs. count the flashes that follow, write them down until they stop or repeat (you may have more than one code). Then press the button again and hold it for 7-8 secs. Report back with the results.
