OBD-1 DTC Codes????

[Hood93z]

I would greatly appreciate anyone's help I pulled codes off my truck today it has a stumble once it's gets to running temp.

1994 Chevrolet K1500 ECSB 5.7L V8, converted to 700R4.

The only thing I haven't replaced on the engine is the water temp sensor for the gauge (the gauge doesn't work)

Now if I let it sit for about 5-10 mins it runs great even if it's still warm my codes are

33, 45, 59, 66, 67, 73, 82

I've looked on several websites and some codes are different I'm hoping to get the correct ones

I've looked at that site plus more and some show different codes and some say that not all of them are compatible with all the 95-previous GM models

Haynes, for the most part, is going to be generic obd codes. Pretty much what's on the internet for free.

You need a fsm to get it all.

Will help in many other areas as well.

Yeah I did my research on it but for the most part the dealership said that my codes sounds right
