Hi All,
Been a while since I last posted but the old faithful has not been so faithful for last few months.
"Flo" has been in and out of the garage for running difficulties. Basically seems very lump when revs are lower, then when you push it, it seems to drive more smoothly. The garage still have not managed to sort this out fully.. and this is not getting me really perplexed.
Some history if this will help:
Car had a cat fitted as standard from factory. This had completely worn out by last year and as was not law to have one fitted I looked into alternatives as the VW replacement unit was stupid money. In the end I had a custom steel pipe made up in Weston and they welded back on the lambda sensor so that it could still read the exhaust gases. Car ran fine for long time up until the winter.
Next symptom... not sure about this but was wondering whether the problem might be wet weather related??
The power seems down on what it used to be and generally is a shadow of its former self..
The car is stock apart from the cat tweak, which at the time of asking on the forum about this, members considered this would not affect in any way the running of car. Thats why I went for it saving me quite a few hundred.
Car generally feels lumpy, coughs and then seems to clear its throat as it were when you put the hoof down a bit.
I have tried the "Italian tune up " (warning about this was listened to as its had a recent cambelt) and really heated up the top of the cylinder head for a bit by caning it on the motorway (its okay.. was late and hardly and traffic about). The hope here being to decoke the head if its had a bad carbon build up.
I am stumped now, and would really welcome some suggestions, opinions, and pointers from anyone that may know what is going on here.
Thanks
Adam
