I Have a 94 Mustang GT 302, put her away last fall and she was in excellent running condition, took her out this spring, and still was running strong. Two weeks after I took her out of the garage, she started sputtering at full throttle. If I gently roll into her she will have power across the RPM range, but once I give her the boot, she falls flat on her face. Feels like a cylinder isnt firing. However when sitting at a red light, I can rev her up and she will roar. But when I take off, shes struggling for power. Some of the things that I have tuned, plugs, wires, distributor cap, and rotor, ignition coil, fuel filter, and air filter. Ive cleaned both the MAF and the the TPS, and double checked the fuel filter, because I did that one in the fall before I put her away. I also read that it could have been bad gas, so I ran her out of gas and filled her up again and drove a while just yesterday and still nothing has changed , once I get above 2500 and start to push her she starts sputtering, if anyone knows how to treat this, or has a mind to help me out please do, I enjoy driving this car and both of my others but when they arent right Im not right. If you all can understand, thank you
