dummies as in myself, im very new too being under the hood, or bonnet as we would say of a trans am.

my SES light came on so i found out how to do the simple diagnostic with the paperclip and i got a code 13, the pdf file i downloaded tells me this is an oxygen sensor problem.

now usually this is where somebody tells me too disconnect something from the sensor but its gotta be even more basic than that, lol. ive got a haynes manual but my friend who has a V6 firebird currently has it. Ive got no idea where this sensor is inside the engine bay or what to do. Do i try simple things like checking for loose wires, or cleaning the sensor etc or is it a bit more complicated than that ?

if anyone could post a picture of the inside of their 305 TPI engine bay pointing out the sensor and how to go about fixing it i would be very grateful

the o2 sensor should be in your drivers side manifold, its one wire see if its there thats where myn is on my 350 tpi and there the same system so sensor should be same place

 

go buy a new one and you will know what it looks like.

they are cheap and will also help with your mpg

take the connector off and use the closed end of a big wrench and put the wire through the wrench and get down on it

 

well i went over too tpiparts.net too see if i could find a picture of what im looking for and found this



then i went and had a look under my hood but couldnt see it on the drivers side around the manifold, heres a pic of my engine, can anyone help me out by circling the area in question, i didnt want too start pulling at things etc incase i accidentally knock something

 

i think i found the o2 sensor, its quite low down, how do i go about removing the silver but thats plugged into the manifold ? can i just grab onto it with a pair of pliars and pull it out and just unplug the black connector thats at the top ?

 

it unscrew out...you need a wrench..

 

Wrench size 7/8 inch(US, lol).

 

just noticed the shape of it yeah, doh, sorry loudmouth i should pay more attention too your posts!

i thought i was using a lot of petrol, i know these cars are known for drinking the juice but mine really was using loads, hopefully a new o2 sensor will help my MPG then

 

looking at that engine bay, i would probably go ahead and do a tune up on that GTA. Plugs, Wires, Dist cap, PCV valve. That should help your milage as well.

 

haha dont worry about it, we all learn sometime or another

 

cheers guys.

battman, my thoughts exactly. i hate opening my hood because i have too look at that everytime i do. the last owner who started the knight rider conversion decided to start painting the engine bay too without masking anything up, theres black paint everywhere and the whole engine is generally grubby.

the only thing ive done so far is put a new airfilter on, ive also replaced a few hoses and a metal pipe which were rusted too hell, i think im gonna put all new hoses on over the summer, ive also changed the oil and oil filter, ive got new plugs, HT leads and belts, just waiting on getting it into a garage to get them done properly.
