Thanks heaps guys, they are really helpful tips :o)

Hi, I recently purchased an '89 SX hatch with 4AGE motor. The car needs a bit of TLC!! One problem is erratic idle. From cold the idle surges between 1500 and 2500 rpm. before slowing after a few minutes but still surging at lower revs. Any help with likely cause/fix would be greatly appreciated. Thanks in advance. Cheers, Dave
