Question about Chevrolet Corvette
I have an 89 tune port injection corvette that starts up and runs smoothly but , will randomly shut off while driving. It occurs at highway and town speeds and does not idle rough or have any other problems I can think of. After a few minutes of waiting you can easily start the car and drive it with usually no other issues. I thought it might have overheating issues except that some times it runs fine with no problems at all temps and then some days it will just be driving at speed and die. Any ideas what this could be. P.S. we already changed the injectors to no avail.

Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

The injector could definitely trigger a misfire code, but you also mentioned that you had a mass airflow sensor code , that code code be responsible for te sluggish moment of the vehicle and rpm going up and down. However if you have a misfire onCyl#6 and the coil and the plug is good the ONLY other thing to cause a mis-fire would be the injector. To check the injector get a NOID light, you can get one at almost any auto-parts place. To use unplug injector plug from the bad injector and connect it to NOID light the light should have a steady PULSE/ligt flickering. If light flickers fine then injector is bad and will need to be replaced. If light doesn't flicker or flickers intermittently then you may have a bad wiring to that injector. Check if wiring is good, then you may have a bad cam sensor or sensor gear. Good Luck and contact if you need more help. Thanks for using FIX YA

You will need to Change your Thermostat. A bad Thermostat will cause the Overheat Problem as Stated above. Also, Check you Coolant Level, and see if the Water Pump is Pumping Water through the Radiator. Please Rate my Response, I need all the Help that I can Get! Thanks!

it'll either be your ignition system (spark plugs, distributor cap, etc) or more likely your fuel system (most likely your fuel pump or your fuel filter)
