blew my 350 engine back in April. My brother in law gave me one he had for his NASCAR racing that only ran 60 miles in one race. I kept my old tbi but I rebuilt it and bought remanufactured fuel injectors for. I've put about 800 miles on and I am getting 7 miles to the gallon. When I goose it to pass someone as soon as I let back on the pedal the check engine light comes on and now it struggles. Going up hill it can slow down too 40 miles an hour. If I pull into a gas station idling in gear it will feel like I am pumping the gas and letting go.
I check one plug from each side of the engine and driver side it looked wet and passenger side look normal to maybe a little burnt.
