The past few days my idle has been surging from about 700-1300RPM back and forth, back and forth..

Car is a 93 Si with 163k and like i said, it ONLY runs funny when its idle at a hault.

Just wondering if anyone has seen this problem before or could help me out. Thanks!

 

Just forgot, put some fresh NGK's in there about 6 days ago......but its been runnin funny past 2 days........

Just a little more insight i guess...

 

need more info about the car.. but check your tb, either that, or you have motor issues. good luck

 

My guess is a vacuum leak...

 

good call.

 

Alrighty..........maybe Burke (htmember) can take a look at it for me. He's a whiz with this stuff. Thanks for the help though.
