the cable for some reason was wound all the way out (thus the higher revs)
i cant seem to adjust the duty cycle too much anyway - too rich and it stalls, too lean and it just stalls again.
would the oxy sensor alter idle speeds? i am assuming that due to the fact it makes no difference to the car with or without my o2 - then it is faulty? ....
the problems just keep coming! thanks so much for your advice though i really appreciate the help!
