code 13 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

hope some one can help with this one.

when your kinda cruising on flat ground barley on the fuel you can hear the engine change tones then the check Eng. light comes on. it will stay on till you give it some gas and get after it then the engine will change tones again ( like your clearing it's throat) light goes off.

it sounds kinda like a carburetor loading up.

it's gotten so I can make the light come on and go off. the only code it logs is 13

any thoughts

Thanks in advance

Code 13 is oxygen sensor issues IIRC.
