After pondering to no end my tip in hesitation problem, not coming up with anything on my datamaster logs, and talking to a couple of people, I think this is the problem I'm having. I would like to know from anyone who has had this problem and how they fixed it. It's the last piece of my puzzle I need to get back on the track. I'm returning home in about 2 weeks and would like to be able to jump right back in and get my car running right.

 

Bump, someone, anyone???

 

Do you have any kind of ignition box? they can cause a problem but usually just how and where the wires cross over other ignition wires. Maybe twisting them around each other will make a confusing enough signal so as to not get picked up.

What you're experiencing is completely different than the "tip in stumble" that people with large injectors can feel. And from what I've seen, it's not as common a problem on an 8 cylinder as it is on smaller motors.
I think what you have is more of a low rpm, high map problem.
Not sure if it's timing or fuel or what though...

 

I really wish I could tell. More than one person has looked at my datamaster file and couldn't see anything wrong with it though. I'm just bumming because I'm not going to be able to get back on the track until I get the problem taken care of.
