1994 Chevy Truck sensors

Check the fuel pressure and comeback with it we start here.

its good so what now

Scan the computer for code/s and then comeback.

BTW what was the fuel pressure reading?

60 psi

ok do i have to have a oxagen sensor

Yes sir-you need the oxygen sensor its job is to control fuel demand during closed loop operation.

thanks so i need to hook one up but all i got is straight pipes no mufflers or cats so what do i do drill a hole and hook one up? would this make my truck run real bad by not haveing one? thanks for your help

my truck is running real bad-what do you meant by this-rough idle or what-

rasmataz:
This cat has been starting new threads asking the same old question about his 1994 truck. He dont seem to listen to what people tell him to check!

I have read ALOT of your replys to people, and have found you to be very good at being able to troubleshoot via the internet.

There is just something about this guy that makes me wanna sit down, smoke a cigarette, drink a beer, watch a chick flick then blow my brains out with a .40 caliber!

*btw cdowd....its OXYGEN, but I will ALLOW you to call it O2

DCS1998 I appreciate your confidence in me. If people will listen to us they might end up learning something instead at times they try to educate us with something we've arleady learned thru experiences and certifying the ASE. In this particular case anything can cause a bad running engine-such as compression/fuel/ ignition problems etc

no it runs good at idel. it just spit and spuders real bad when you drive it.

Check the throttle position/manifold absolute pressure and knock sensors-

hey thanks so much its the oxgen sensor i did a test and it gave me a code the code was 13 which in the maual code 13 says oxagen sensor but i have on last ? ok i can not find were to hook the oxagen sensor up at because some one took it out so ther for i cant find the wire to plug the o2 sensor in at

Heres the wires that goes to the O2 sensor-see below

ok but my? is what if i dont have them wires. becase someone took them off and i dont have cats the y pipe has been cut off .

You need to do something about it-I've given all I got-you need to get a repair/service manual and track the wires.
