My old pre-mod record was 525 and as dp said is was doing about 90km/hr. It was on the way to Carlisle actually for the FocusExplosion or whatever they called it. Automatic BTW.

I've now done about 90km on my tank topped up with 94. I think I'm calling it stumbling now as in fuel straved not deto. Its like a shudder. It is happening periodically and in every gear (usually under load) but also at idle too. I was not able to go above 120km/hr on the way home on the QEW yesterday night, it just wouldn't do it.

I'm still convinced it is bad gas but when one is unsure ones mind tends to wander to things like filters and injectors and even..................automatic tranny problems? What are the symptoms of a bad auto tranny anyway? I nor anyone in my family has never had problems with one before, mind you the is first Ford anyone in my family has owned since the 1965(?) Galaxy. ;)

I had the auto tranny routine service right at 50,000 and fuel filter was done as well.

Thinking about it, it may not have even been bad gas but "really good gas" that loosened some crap that had built up over time?

We'll see it will be weeks before I get through this tank of gas given the amount I drive, I'll update as I find things out.
