Razy......There is no throttle down skrew on my fuel injection engin.,......
I can resolve the idle by way of the computer but to expensive and reves are to close to the normal retting od 750.
I have heard that I can reverse the spring loaded cap in the EFI valve. this will bring down the reves permanently which is ok for a warm climate.
all other points on my car are excelent.
I have disconected the EFI with the reves coming down to 600. this is good for a manual change. but the warning engin light stays on and the air con. won't come in due to the reves being low..... will this be ok.to reverce cap,.. squiizy.
