Calling all GTA owners - important information re. sticking throttle
What with the GTAs increasing popularity, I feel it necessary to bring this you your attention, in the hope it'll prevent something nasty.
We purchased our 156GTA in September 2002. All was well and good until a few days later, when the throttle jammed open whilst attempting to slow for a roundabout. And with 250bhp on tap, that's bad. Luckily it rectifed itself a couple of seconds later. Of course, it soon happened again, and again within the space of a few days.
A little investigation by ourselves revealed the flollowing.
The 156GTA has unique floormats (for some reason are a bit shorter than regular 156 mats), which are only fixed down at the rear (by the seat), leaving the front of the mat (deep within the footwell, underneath the pedals) free to flap around up/down. What with your foot position when driving and the shorter mat, the mat can rise up at the same time as the accelerator pedal is pressed down. The result being the mat rises, gets trapped underneath the depressed pedal, and prevents in from moving back up when backing off. Belive me, it's frightening. This doesn't happen with the regular mats, as the extra length means they "finish" right up the front of the footwell, well away from the pedals.
We cured this problem by velcroing the mat down at the front (a cheap bodge on a £30K car), as both the dealers and Alfa Romeo didn't have a clue.
And the best bit? Upon reporting this to the dealers, the technician turned around and said "Oh yeah, that happened on the PDI test drive..." eek! They couldn't find a cause, so they let the car out anyway... rant
Anyway, I hope GTA owners find this useful...
