i have a 94 4runner with a random missfiring problem and was wondering if i can use a code reader to check my sensors? i was told that u cant use a reader on a 94.

 

code reader = paperclip. nuff said

 

???????

 

and where can i get a code list

 

Dang, beat me to it.

YOu should have a code reader in your desk drawer

If not, strip a short section of wiring and jump terminals.

There is a small black box with wiring going to it labeled "Diagnostics" under the hood. Jump the T1 and TE1 terminals, and count the flashes.

 

Google the code list, and you shall find it

 

where does it flash

 

Check engine light in the dash

 

ok thank you!
