Ok here we go,
For the past 2-3 weeks my 5.0 Mustang has had a weird drivabilty issue. When the engine is cold it runs totally normal for about 15 minutes, once the engine get warm the idle will get progressively worse and the car will run EXTREMELY rough past 2000rpm, and the tach is very bouncy. When you drive it and you try to go past 2000rpm it feels like a bucking bronco.
We have replaced the Ign. module, plug wires, cleaned the cap and rotor, tried a difference MAF. The problem continues, before throwing anymore parts at it I though it would be a good idea to ask if anyone has experienced these symptoms before. I pulled codes 94 & 44 which relate to the secondary air system so I dont think they are relevant.
Let me know what you guys think. BTW the car only has a BBK intake, edelbrock intake manifold, and an exhaust. Fuel and ignition are stock.
Thanks for the help, Bob
