ok so im comin into town and it just starts acting up like im not getting enough fuel im getting code 4. 20,1 and 10 now

 

could we get a little more specific please, exactly what does it do?

 

have you fixed your problem

 

I had the same problem on my ZC a while back, for sure the 4 is a distributor problem, that'll probably take care of most of the codes, 10 if I'm not mistaken is the intake temp, you could be missing, like mine, the sensor on the manifold
