94 Z28 flooding out
 

I have a 94 Z28 with the LT1 and T56. My car will run for about 20 mins before it seems to flood out and die. This issue happens whether its idling in the drive or running down the road. I tested my old cts after replacing it and had acceptable readings and 5.01 v across the plug. The wires from the cts to the ecm are solid and all 3 grounds for the ecm are good. Any one have and other thoughts?

Your opti is going out had the same problem

ALDL OBD1 OBD cable OBDI OBD2 engine codes

buy the cable

datalog the car


my money would be on O2 sensors

thanks aldl cables did not have the one i need but i got one from akm for a lil more money...can you suggest a good free program to go with it?

i have used datamaster

thanks craby.....torgue no o2 codes and readings look good time to pull my opti and check it

so after finally having time to pull my opti, i saw all my contacts were corroded. I cleaned all my contacts and my car stopped running hot and cutting off on me. It would seem the problem is solved...for now. Now time to budget in a new opti
