Hi All..
I am taking the car to my mechanic(friend). We are going to set the
timing on it using the light. He is going to check the book, I read
somewhere that it should be 5-10 degrees somewhere around
7degrees ???. ( factory settings.)

But without a manual, you will have no idea what specs to check for.. > A
manual is a must.. I wouldn't be half surprised if you feedback
carb/computer system is flaked out..

I am going to get a manual on my way home today. I will start off with
the temperature sensor, then work my way to see if I can get codes off
the computer.
One other thing about the diagnosis. I jumped E1 and T on my car got
no engine light at all. All I get is the Brake light and battery
light.
Pulled the Diagnostic cap to see if there was any wires going to E1
and T.. No wires to T. only 3 wires. 1) E1, 2) Vox? 3) O2
Tried connecting the E1 and Vox .. no engine light. Is there a
different way to get engine codes off 88 corolla carb car?


If the check engine light is not illuminated, it is unlikely that there will
be any codes stored in the computer. To get codes, jump wires E1 and TE1.


Well, if the temp gauge is in the appx middle, and it's always been
in the same place, your cooling system sounds fine.
But....It's still possible to have a bad temp sensor.

This morning while I was driving after about 30 minutes, turned the
heat dial all the way and got VERY hot air through the vents. Also I
noticed that the temperature dial dropped to 1/4 level on instrument
cluster. After I turned off the heater, it went back up to 1/2 way
point. It was 23 degrees this morning in Toronto.
Not sure if it is supposed to drop that much.?

You are describing normal operation of the cooling system. It is probably
OK.


There should be an electrical connector for checking the oxygen >sensor
without disconnecting it. Unlike the sensor, this connector >puts out
hefty pulses and can be read safely even with a cheap
analog meter (can overload an oxygen sensor if connected directly).

I took the reading of 0.1 Volts from the wire that connects the O2
sensor to the male/female plug. Not sure if that's what you meant.

When I changed the original plug about a month ago, there was no white
deposit.. beside me putting 94 Octane on a carb car..(darn emissions)
I did not do anything different. So toyota Denso plugs should be
better for the car.
Again, I have learned so much within the last 2 days. I thank you
all ..
Once I figure it out.. I will post my emissions results so, others can
learn from it.
Des.
