    Ok, same setup as in my sig, I will get up in the morning and take off in my car (no warm-up). Head to the 7-11 about 3 minutes away. Shut the car off and go get cigs or whatever, come back out and start the car. At low engine speeds, when I give it half throttle or full, doesn't matter, the car will jerk back and forth, really bad stumble, as I climb rpms, the stumble gradually dies down and I'm near 5k before I no longer feel it. After the engine has gotten warmer, the stumbling stops. This is the only condition that I can emulate for the problem, but the problem is intermittent. Timing checks out + whole ignition system. No CELs at all. Nothing major had been worked on or replaced before this started happening. Our mornings have been around 62 degrees when this happens. Any ideas guys?
