Humm, after going into gear huh, not up top? I think I do recall that with mine too way back when before the rear gear changes. It felt as though there may have been too much ratio change and the rpm's would drop too much making it seem like there wasn't enough gear. This would make it so it wouldn't recover the drop quite enough to be smooth or responsive when I was shifting. Of course if it was spinning the tires it wouldn't do it.CatmanJJ said:
I've had 4.30's, 4.56's and now 3.73's in mine and it was not there with the 4 series gears at all but since the 3.73's I haven't had much chance at romping and banging gears. I'll have to get it out soon and go romp it and see, that's a good enough excuse to do that, right?
Well it depends on when you get on the throttle. From what I have read, the mach's have a "fun" computer. Sometimes when just driving normally and you just start "driving spiritedly" you will get this hessitation(can't spell). Something about the car and computer not ready for it and so it's kind of a defense mechinism built into the computer. But from a dead stop and full accell you will not see it. People installing superchargers have had this problem..because the hessitation is "easier" to notice when getting on it from a roll. Vortech and I think SCT have fixed this error on their tuning. Some machs have it worse than others.
Any possibility it is fuel related ?
Houston runs the RFG fuel for emmisions - I wonder if that affects it.
The other thing might be if the IAT ( Inlet Air Temp ) sensor is sensing the warmer temps , and backing the timing off .
Just some random thoughts.
4.30's , huh ?
Not a good mix w/ an A4 tranny - like I have !

If your skipping up top in the rpm band that would sound to me as you may be running a little lean. I see you have a catback and drop in filter which really should not cause a lean condition but not all the stock tunes are the same. Have you had your air/fuel ratio checked? If possible get that done and see what kind of reading you get there.00VERT GT said:

I'll buy into this theory. I get the same hesitation, but it seems to happen more when I'm driving mellow, windows up, A/C on, etc., and decide to tromp on it.
When the weather is cooler (70-80), windows down, A/C off, the throttle body seems MUCH more responsive. When the temp drops to 50-60, the motor really seems to perk to it's peak. A cool front came through yesterday. Today, I wasted a lot of fuel 'feeling' the Mach
