Full Version: Problems With 1st Gear

Right - Had the car for about a month now (Altezza RS200 Z Auto) and after a few initial problems (O2 sensors not plugged in!) I have started to get used to the way the car drives and how to push it to get the best out of it. Tiptronic is great for holding it in 2nd gear at about 30-40mph then flooring it!! :D

I have still got one problem that I can't find a solution for in the forums (I've PM'd a few people with similar problems but only had limited responses)

The main problem is I am unable to floor the accelerator in 1st gear (either from stationary or dropping from 2nd into 1st). The car revs to about 4-5K and then won't push any further. The engine is still running but there is no response from the gas pedal. During this there is a ticking/clicking sound coming from the engine bay (I think on the drivers side). It's almost as if something is restricting/limiting the car but it only occurs in 1st gear

As soon as it's in 2nd the car pulls through all the rest of the gears with no problem.

If I floor the gas pedal in 4th or 3rd gear the gears drop down and the car pulls nicely - except if i'm in 2nd and the car drops down to 1st.

I have been using the 'Snow' button and with this on the car accelerates through ALL the gears smoothly - obviously the engine doesn't rev very high.

Does anybody have any idea what could be causing this??

Happy New Year to everyone B)

I believe the problem is caused by the traction control limiting the throttle.

I am driving the MT version and I have the problem of complete throttle cut-off when drifting out of a corner. I floored the throttle but the engine simply just idle away or the engine rev is somewhat intermitten until the car pulls out of the corner cleanly. :yawn:

Makes no difference with TC on or off...

Seems better some days, but just when I think it's gone away I go to pull away or drop down a gear and the engine doesn't do anything.

If I keep my foot on the pedal, I have to wait maybe 5-10 seconds before the revs will jump up past 4-5K and into the fun stuff!

It's almost as if there is some limiter stopping the engine reving past 4-5K. Bl#@dy annoying becasue I have to be REALLY light footed until I get to 40mph and second gear kicks in then I can floor it (in the meantime every granny in her Fiat Panda has passed me!)

I've tried it with the SNOW button on, and it doesn't happen - obviously the engine is reving as high, but it does mean that I can floor the pedal from standing without any cutting out/limiting
