hey all,

I recently purchased an XR6 T, 2004 (AUTO). The car has been great, but has a problem. When I first drive the car in the morning, or after I havent driven it for 4 or 5 hours, the acceleration at first is extremely jumpy. You put your foot down, and there is little response... followed by a jerk of power, then it cuts out, then more power... it kind of jumps in and out for a little while. After about a minute, it goes great and drives normally, and doesnt have any problems till I leave it be for another few hours. I took it to the official ford service place in Sydney two days ago, and they went over the car, cleaned the injectors (which they thought it was), but this morning the same problem. So they didn't fix it. The problem was of greater magnitude with the AC on after work tonight...

The car has been fully serviced recently as well (2 weeks ago). The car is still under its 3 month warranty, so if anyone could help with some ideas as to what it could be, or even recommend a servicing place in Sydney, that would be great and much appreciated.

this is the third Falcon ive owned, this being my first XrT. I had a similar problem with my EA a few years ago, and after going through several car garages in melb to know avail, it was finally worked out that the oxygen sensor caused the jumpy acceleration.

The car is great otherwise, but this doesn't feel right.

Thanks in advance,

Simon.

Could try a bit of WD40 on your actuator !

Could be the o2 sensor or may even be one of the coils.

I had that problem in my Volvo truck and it was found to be a dodgy accelerator pedal position module. part of the fly-by-wire system. replaced it and it was fine then. might pay for them to have a look at that.
