Yes frank l'm about 6corner plastic black screw near the TPS plug i turn it but there is no result... i want idle at 750~800 ...I've clean neutral valve and changed o ring on it... also resoldered maf sensor..... nothing more

the ecu is probably over-riding your 800 setting mate, its programmed to 650 ish eh
have you retarded the spark ?

No timing is standart.......I took off the throttle body cleaned all ports and find that there was leak from maf sensor cower which I sealed with Dyson ( windshild black silicone) after resoldering... now I'm gona use epoxy glue hope it helps....

Idle adjuster screw was tightened up too much also.. so I will wait for morning glue will dry and try to adjust idle.... thks Frank
