i have a 91 camaro with a 305. I have replaced the following: fuel filter, plugs & wires, cap & rotor,EGR, and throttle postion sensor. If you hold the gas down a little it will stay running but as soon as you let off the gas it just cuts off. It's not making any noises and while you keep it running the engine sounds good(no skips or vibrations), and once you get it moving on the road it will go fine but its lacking in the power department. It feels like its running out of gas. I've run the codes and keep replacing parts but with no improvement.PLEASE HELP. im a single mom with not enough funds to put it in the shop. this car is my baby, cant live without it, any advice is appreciated!! thanks!!
