Adjusting the handbrake is really easy. Assuming the pads are okay (I've 
seen them where the pad material has fallen off the plate, but that was 
a once only) It's a 5 mintue job, including the time to take the wheels 
off. Unless the cable has become unhooked from the yoke on the handle. 
Either way, it won't cost anything in parts to fix. I've yet to see a 
snapped cable.

Lambda system not working or sensor has failed. Alternatively the 
"mechanic" has mucked about with the mixture. It's runing rich. Usual 
culprit is a failed lambda sensor, wrong relay in yellow* socket (should 
be 2x 15A), failed control pressure regulator, though usually these fail 
lean. You can eleminate a lot of possibilities by telling us if our 
frequency valve buzzes. It's just under your air box on the right hand 
rocker cover. SOunds like an angry cricket.

Exhaust crossover heatshields are loose. A really simple fix (because 
the bolts usually break) is to wrap a couple of hose clips around them 
and the pipe to hold them down. Could also be a missing bolt on the 
right hand end of the main rear box heatshield. It's a sod to put in, 
but if left off, rattles like a good-un. Manifold heat stove also a 
possibility, but the crossover heatshields are the most common

Some cars have problems with the wheel rubbing on the anti-roll bar. 
Look for a shiny spot and there's your answer. Unless you mean hard 
cornering at speed? If so, and if, as you say below, it also does it 
when throttling back, check trailing arm bolts and all ball joints 
(depending on whether it's coming from the front or the back).

Original pressure gauge senders are crap. Remember you do also have an 
oil pressure light so you can trust that. Most cars make do with just a 
light.

Check the pin switches are plugged in. If the interior lights work, it 
ain't the fuse.

Check for play in the steering joints that go from the bottom of the 
column to the rack. Are you sure it' a proper "new" rack? Check when it 
was installed that the right-hand (square) bracket has located the 
flange on the rack into the two little tongues on the plate beneath it. 
It is possible to install so it allows the rack to move.

There are quite a few owners out there with "rose tinted specs" who 
think their car is better than it is. My car is my pride and joy but I 
really would like to rery and sell it! :-) (it does have strait bodywork 
though <grin>)
