Trouble is, there is only one thing worse than a stall and that is a random stall. I had that on a borrowed Vauxhall Astra automatic and it's damn dangerous, as other drivers are predicting where you'll be by the time they get to the same place!JAC said:So, after a a few days of driving the car normally, it still stalls now and again, but it seems to have gone back to it's old self which means it only does it occasionally and at random times (normally at the most inconvenient times )
Could be anything, just be wary of any 'Sounds like the coil pack to me' guy as I'm sure he's related to the same 'Sounds like a virus to me' guys who used to give that universal answer to everything in the early days of the Net.
I can't say I'm aware of any sudden 'kick in' at 4K, mine is alert and responsive right through the rev range and the pick up is instant. Certainly my 0 - 60's are as good or slightly better (early Pumas don't have a limiter on 1st and 2nd) as they should be - I practise these every so often, so I'm ready to very quickly bail out of trouble, if required.JAC said:When I got the car, you could really feel the VCT changing the engine at around 4000rpm. However, now the engine power is just one long smooth acceleration. There is no lack of power at any rpm, but accelerating from low revs all the way up to the red line there is no notice in change in the engine, just like any normal engine. I'm guessing that this is a good thing, but could you confirm that this is the normal behaviour of the Puma 1.7 when running properly?
Two things, back in the day any fast/brisk car was distinctly unhappy at 2 - 3Krpm. I recall sometimes dropping to 2nd just to stop, what seemed like, the ill-tempered camel continually complaining that he wanted 4K at least. With more modern and, and certainly with the Puma, you don't get this. At 3K you could genuinely be driving a happy, contented Astra and be somewhat initially surprised by the brisk response you get when you put your foot to the floor.
The reason I mention that is this - from what I understand (i.e. could be wrong) the ECU continues to 'learn' after its initial reset. It's possible that it's learning whether you prefer economy/sedate or performance, etc and so a Puma that hadn't been floored much by its previous owners might well initially have a more pronounced 'kick-down' feel at 4,000+ ? I seem to remember that when I got mine, 2.5 years back, that it did this, but these things are subjective.
Merry Christmas,
