heep70 Posted March 20, 2004 Share Posted March 20, 2004 My EA82 non-turbo pings on acceleration and while at cruising speeds. I have timed it back to 6 degrees. Added octane boost. Unplugged EGR. If I give it gas while it pings (cruising) it will go away. Its almost like it is getting to much vacuum. Quote Link to comment Share on other sites More sharing options...
GLCraig Posted March 20, 2004 Share Posted March 20, 2004 When you say Unplugged the EGR i'm assuming that you mean you cleaned out the EGR valve. Did you also clean out the tube as well? Also check to see if your EGR solenoid is working. Quote Link to comment Share on other sites More sharing options...
rallyruss Posted March 20, 2004 Share Posted March 20, 2004 yeah I am confused about the EGR too. EGR should reduce cyl. temp and therefore pinging too. try 5deg. my 85 gl would not take any more than 5 deg of advance. seafoam carbon cleaner may be helpfull too.

speedbump Posted March 20, 2004 Share Posted March 20, 2004 try pulling back to STOCK timing (?? BTDC) remember to unplug the vacuum advance! Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted March 20, 2004 Share Posted March 20, 2004 Exhaust leaks can sound like pinging.... just thought I would toss that out there. Doesn't sound like that's your problem tho, since it goes away if you lay into the gas. Generally and exhaust leak will get louder when you do that.
