thanks metal storm , its been a long journey and a bit of bad luck recently. what with the fuel tank and I now also have to make a stabilizer bar to fix the mount on which the crank sensor sits. it tends to vibrate under load and the ecu read crank trigger errors. luckily it corrects its self some 10,000 times a second but still need to minimise it to a acceptable level.
I have re-read a lot of the posts as I haven't been on it for 4 months. will change the ign to be more in line with firebird and cobalts info. just struggling with this rich idle ??
