Hi, thanks in advance for your help. I have a 1998 Ford Escort Sport with around 100000 miles on the engine. It runs fine except that on acceleration at lower rpms the car wants to jump a little. Once the rpms come up it goes away. It sort of seems like it's misfiring, but it's more of a random misfire. I've replaced the plugs and wires. Also, the PCV valve housing and hoses were melted so I replaced them. Could this be a mixture problem and if so, what would be the most likely cause?
