I have a 1992 Corvette that hard to start when hot
I have a 1992 Corvette that hard to start when hot. The starter rotates the engine fine, if I press the gas pedal all the way down it will start but will die if I release the pedal but if I keep the throttle at above 2,200 RPM for several minutes it will eventually run fine till I turn it off. When this happens I have observed that the digital coolant gauge will read LO or just some gibberish.
At one point I thought I could have water in the gas but I pulled about a quart from the fuel rail shredder valve and found no water.
I just installed a new OptiSpark and in the process I broke the coolant temperature sender so I replaced that as well.
Any thoughts?

run a fuel pressure diagnostics test. i'd suspect leaking injectors, but just guessing....

Look at your temp sensor for the digital and connections and make sure coolant is full and burped.
