Corolla 1994 Gli Idle Problems

[haddock_n_chips]

Hi all,

im new here so be nice!

I have a 1993 Toyota Corolla 1.3 GLi 16v, with 85,000 miles on the clock (nice and low !)

But i am finding the idle speed a bit too fast. When cold it idles around 1200-1400rpm which is fine if the engine is cold, you would expect it to be high in order to warm it up and get it going!

But the idle speed doesn't change even when it has warmed up! I drove about 100 miles yesterday and it idled between 1200-1800rpm at the beggining, middle and end of the journey!

Also the fuel consumtion is worse than my 1.8cc renault! Do you think the high idle speed is causing the excessive fuel consumption?

How can i solve this problem? I am no expert at mechanics but i know a little, and i have a copy of the haynes manual! I don't have any way of connecting the ECU up to a computer to get error read outs etc...

thanks for your help,

WiLL......... :)
