Okay, now some of you seem to doubt I can set my own timing right so juuust incase I may have done something wrong in the past I reset my timing. Mostly out of self doubt. I used a tach/dwell meter to monitor the idle RPM and used my Panasonic timing light to set everything just right. Once the engine warms up and after about 1hr of driving, the pining starts up again. I got a feeling it maybe heat related, but I have no idea. I tried bleeding my heads again, but that didn't do anything. I ran combustion chamber cleaner and several bottles of Techron concentrate to see if it was maybe hard baked carbon causing my problem. I still have the problem. Pleaser don't suggest I look at the EGR or for vacuum leaks because I've already looked at all the usual suspects. I still can't get the thing fixed. :-( Kenichi 94' Sentra E Ga16DE www.importpartsplus.com
