Help!!
I have a '94 LT-1 with 14,000 miles. About 2000 miles ago it started to have a hesitation with medium to heavy throttle, Plus a rough idol. It feels like its going to stall. Runs good above 50MPH
I have:
Changed the Opti (fixed the problem for about a month)
Changed all the plugs and wires, plus ran injector cleaner through it(ran two full gas tanks with Techron additive because of the cleaner) fixed the problem for about another month
Both problems started again this afternoon
Any ideas? Bad injectors?

might want to check/replace the fuel pump and filter (both in the same spot). I had a similar problem but ended up replacing the opti, coil, WP and FP/FF so I am not sure exaactly what was causing my particular problem. Run some injector cleaner through it. Also does it seem to do it when the tank is low?

Unplug the coolant temp sensor onthe front of your waterpump and clean the terminals inside. I had similar symptoms and that was all it was. a dirty connection will cause the sensor to read -93 degrees or something like that.
might not be your problem but it takes 5 seconds to do.
