[madseacow]

I'd say you have leadfootitis... commonly caused by having a fun fast car

do u mean like gas is coming out the tail pipe or u get $hit for gas mileage, cause if u expected to get 30mpg because this car is called a sport compact, then srry, u bought one of the gas guzzeling bad boys of the 80's.

Check O2 Sensor. I changed mine and it got waaayyy better. I just got over 300 miles per tank. btw, its 87 NA.

best place to find a replacement 02 sensor? for our cars....

 

[supraaddict87]

check the for sale section, i think its mdcmotorsports that has direct drop in units for about $30-$40. Or if you want you can get one for a eary 90's thunderbird or mustang, if you can make it fit

what's the difference?

I got one from Autozone...... I think its working well..... You trying to get better quality one or just didnt know that Autozone sells it for 40 bucks?

 

[YoNkErS87t]

is the autozone one a universal or does it fit right in our harnesses???

 

[Supraholic]

does the One-wire sensor from Autozone fit the turbo cars with three wires?

are you sure you aren't running rich ? do you have an a/f meter ? i was running way rich for a month or so ...mileage dropped to 13-14mpg . i checked the o2 even replaced it, cold start injector, and some other things finally checked both vsv switches both some how got toasted since the last time i checked them . i replaced the fuel vac one 1st and it was better for about 10 minues then slipped right back to rich . after i replaced the egr vsv it settled right to where it should be and mileage went to 16 mpg . a few miles per adds up

Ive got one that fits right in. They had another type which less part which does not fit right in. I do not know about o2 sensor for turbo since i own a NA.

That is probably 20-22mpg. I get that in my 89 N/A. 15mpg around town, a/c on all the time here in the desert. I know I run a bit rich, but its better than too lean.
Universal O2 will work for N/A, there is an adapter plate available to bolt it in to the manifold.
