Well following on from this thread I tested my TPS using a multi meter and Autodata instructions provided by Cully here: http://www.306oc.co.uk/forum/attachment.php?aid=6617
The results are...odd I can't figure it out.
The voltage seems to be changing smoothly with the movement of the TPS as it should, but the values are way off? According to Autodata it should change between 0.2V at closed throttle and 5V at WOT. Unless I'm being a complete retard (which is quite likely) mine only seems to be like 2.3 - 5.9mV? I don't understand why it would seem to be working as it should but only like 1000 times as weak?
The other thing is I can't seem to get a 5V supply voltage but I was measuring that wrong (measuring with TPS plugged in rather than measuring multiplug directly), will double check that tomorrow.
The car definitely feels better to drive with the TPS unplugged so it must be faulty in some way.
