drivers side ex. manifold

cjcland

is it down about 1 foot coming strait out towards the outside of the car and by replacing this will it fix the code 44, i recently had the fuel filter changed and it still runs like crap and checked the codes and it came up 44 so I thought i would change the o2 sensor and see if it worked

Driver side exhaust manifold. I beleive it points forward. You should be able to see it from under the hood but you can't miss it from underneith. It is the only thing that taps in the exhaust manifold. Keep looking, its there unless it fell out.

is this the o2 sensor this pictue is to the rear and down a foot or so on drivers side the arrow points towards the front of car

nope thats not it!follow the ex. manifold to the connection of the drivers side y-pipe,at this point you will see,feel the o2 sensor it has one wire coming from the dr.side motor mount to the sensor

cjcland

this does have only one wire and point kind of forward at a slight angle towards the fender----and will replacing this fix the code 44 problem ??

thats it!it looks relatively new but it can still be bad,if the o2 sensor has been bad long enough it can kill the map sensor,dont forget to disconnect the battery before you do your work or the problem may still exist in the ecm.

cjcland

so if i change this o2 sensor will it fix the code 44 problem?

Keep the receipt if it does not fix your code 44. Make sure to disconnect your battery (will erase all codes stored in brain) after you install the new O2 sensor.

Only if it was due to the sensor itself. It could also be caused by a short to ground, the motor being lean for an extended period of time, or air finding its way into the exaust stream (probably not as much of a problem with manifolds).

well i switched it out and i am still having trouble it runs real rough when first starting, surges up and down and then kind of smooths out once warmed up but still a little sluggish so far i have changed the o2 sensor, TPS the brain box and fuel filter and im still having trouble im going to change the coolant temperature sensor next to see if that fixes the problem, probley get flamed to death for saying this but never had much trouble with the 302 in my mustang the camaro has been one thing after another ( still love the car though, just frustrated)

What year and type of engine is this? The 8th character from your VIN would help.

cjcland

its a 91 rs with a 305 5.0L im pretty sure its a throttle body injection, it has two jets that sit on top and spray directly into the carb. 8th character is an E

Yes, should be TBI.

You might get more help over on that forum.

OK Here is a list of all I have done to try in fix this problem

new brain(computer) same chip
TPS
CTS
O2 sensor
air temp sensor
idle controler
fuel filter
new cap and rotor
new plugs and wires

after replacing the plugs and wires and cap and rotor it runs alot better, but its still rough idle at start-up and has a hesitation when you give it gas from a stoplight or even if i am already moving there is hesitation.........im running out of ideas here

Maybe bad head gasget? pull your plugs see if any have a green tint to them.

Check the TPS and IAC by reading up towards the end of the "new to TBI" sticky. Dimented goes into great detail on adjusting your TPS and IAC. The IAC can cause your car to run like poo if messed with. Does the EGR valve move freely? IS it gummed up? What is your fuel pressure?

cjcland

Its Fixed !!!! heres what I did i had a mech shoot some fuel injection treatment directly into the fuel lines to clean the injectors and now it runs like a champ, thank you so much for all the help on this forum and i hope this helps someone else who is having the same problem

how much does an o2 sensor cost and where can i find one?

Big AL91

From an Auto Electric (speciality) Parts Store, get a Standard Plus, USA made under $25.

Benm109

Oxygen (O2) sensor for our cars usually cost between $10 to $20. You should be able to get them at any auto parts store.
