It was the Relays !!!!
Well after all the parts they put in, MAF sensor, Computer, intake Gaskets,Fuel Filter and flushed Injectors, it still stumbled at 50 MPH.It ran rich and code was low voltage MAF sensor. We took your advice and had them change both relays behind the battery on firewall, at their expense i might add,and the engine light went out and the car is running great.
One thing i do notice is the car starts immediately when cold or hot, but if she sits for 30 to 60 minutes it rolls for about 3 seconds to start then it is fine.
I have a question for you out there.Could the faulty relay burn a MAF sensor? I also had them give me back my original Maf sensor and computer as i think as you said the problem was the relays all along. I also gave this addy site to the (Mechanic) i use that term lightly. Oh and by the way they didn't have a FSM for the Vette !!!!. Just want to thank you again, this Lady is now riding around in her Vert and it is purrrrrrrrrring !!!!.............................Lacy
