Malaysia will start the seventh round of A1 Grand Prix at Eastern Creek from tenth on the grid, but only after a frantic weekend that has thus far been blighted by Alex Yoong's failure to get to grips with the Australian circuit, as well as several mechanical problems.

Eager to recover from a brace of disappointing recent results, Yoong had high hopes heading to Australia after scoring good points there in 2005 but instead found himself some two seconds off the pace in practice and well outside the top ten.

Nonetheless, while much of those problems were eventually traced to an electrical glitch that forced an engine, Yoong admits the loss of reserve driver Fairuz Fauzy on hand for testing duties has also had an effect.

"We've had a challenging weekend so far, not only with missing the first practice session as we don't have Fairuz this weekend, but also with an engine change and bedding brakes taking time away from development work, mechanical issues curtailing our practice time and then we had some set up issues.

Nonetheless, Yoong struck back in qualifying and although tenth place is not the best the former F1 driver has managed this season, he was nonetheless pleased to have made a significant step forward.

"It was only this afternoon that we got ourselves back on track. With all of this, I guess we must be satisfied with tenth, but we all know we have a better car and performance potential than we're showing."
