Hi

 

have red gs300 1997 it is going like on 5 or 4 on idle.

so changed distributor cap, leads and sparkplugs , it worked fine for 2 short trips 2x 4 kilometers,

today i drove it first time longer 120km and now the problem is back :(, as it is almost the same engine as Na supra only that it has sh*^tty EGr vealve system.

 

any ideas to get this problem solved?

 

it runs well on highway on higher rpm

 

when on idle it sounds lik brup, brup, brup, brup and the longer it idles the lower the rpms go even stalls
