running rich?

[simon84]

I have had a few comments from people about the foul exhaust from my tercel in the past few months. A friend on the coast with a tercel just relayed a similar story and thinks her tercel is running rich.
Any tips on how to change/set the fuel misture?
Otherwise my tercel runs pretty good for her age and 320k on her second motor.

thanks

O2 sensor?

AAP diaphragm ?

Plugged EGR?

[simon84]

where is the O2 sensor, and how does one test it?
How do you replace the AAP diaphragm? Can you get that part or is it part of a rebuild kit?

Thx

Best bet is to SEARCH. Since it runs good and it runs rich you probably don't have vac leaks. Might have a plugged EGR. As far as the O2...you can find the wire on the pass side near the wheel well and you can put a digital multimeter on it to see if it is cycling right...think its 7Xs in 10 secs...it's in the FSM. DON'T disconnect it...just slice a bit of insulation off the wire..but not where it has the grounded cover...forget whether the Terc has this.

As to the AAP...not saying it is not available separately - just that I was never able to find it by itself.
I found it only as part of the GP Sorenson kit, mentioned here in several threads. The number is GP-Sorensen / Carburetor Kit 96-612, as shown in AutoZone and Advance, and probably in your Canadian Auto/Princess Auto stores (I'm naturally unfamiliar with them).

Lots of threads here in the Club as well.

Thanks for all the help.
I tried using the SEARCH and found some info.
Can anyone let me know how to download the FSM?
thanx
