ST is alive again..

[ray]

Fixed the hole and removed the rust from the tank and rebuilt the fuel pump. Added fuel, new battery and crossed my finger's and turned the key...........it's alive again after 6 years sitting idle, but have a MAJOR problem.
The idle is erractic, causing rev counter to jump but not a misfire. Pulled out the ecu which has two led's (red & green) which flicker when the idle jumps, any idea's guys. I remember having this issue when i first got the car when fitting an alarm system to it. I had left the ignition on when i reconnected the battery and this caused the same erractic idle then, drove home but did not have time to look at it as i was going on holiday that night so i disconnected the battery as i would be away for 2 weeks to keep it charged . When i returned from holiday i reconnected the battery and all was well again. Thought i had spiked the ecu and the disconnect had allowed it to reset but no such luck this time....HELP !..

Probably a case off clean up all electronic connections and a thorough service first off 6 years is a long time sat idle

I have started at the battery first. Fitted new battery terminals and cleaned up alot of the earth terminals but still have the problem. I know the leds are to flash codes to diagnose problems but this eractic idle is a bit concerning. I think i will check the dash wiring loom and ecu's.

try to swap the ecu with friends ecu first.. i have this problem before.. swap with friends ecu and confirm it's the ecu fault..

Was hoping it wasn't the ecu as the chances of get one never mind a lend of one are virtually zero.....I will just have to keep trying other things....
