too much fuel
hello guys here's my issue. After initial start the vette runs well. 10 minutes later it acts like its flooding so much that you got to put in neutral to burn off the excess fuel. I've checked the air flow sensor, cleaned the k&n cold air filter, plugs look good, have great fuel pressure,and the car is not giving me any codes. Its a standard transmission. The previous owner said it was dyno tuned. Thanks for your time.

It acts like it is flooding or is it actually running rich? The problem probably happens when it goes into closed look once the engine warms up. Do you have a scanner? A car running crazy rich could be anything from a exhaust leak, O2's to the ECT sensor.

ran rich before I cleaned and oiled the filter. It runs bad at takeoff. At higher rpms that car runs great. Infact its crazy how much power it has. I changed the mass air sensor,new plugs,etc. Here's a stupid question.how do I find out what type of computer mod was done to it? Also how do I get rid of said mod if I don't know the source. Thanks guys I appreciate your help.

Only way to see what was done is to open the ECU file witha tuning program HPtuners/EFI live, ect.. it can be flashed back to stock by a Dealer or retuned by a tuner using a tuning program.
ANOTHER option would to get another STOCK ecu, sync the key and run it on a stock ecu to see if your troubles go away.. BUT you need to make sure the injectors are stock or you will not be able to run the car unless they are setup for the the correct size injectos?
What mods are done to the car? Stock injectors?
Sounds like a tune to me.
