Hey I adjusted my valves a few daysd ago. They were extremely tight and were causing me to run rich and run a low vacuum at idle.

Anyway i adjusted them to factory specs, but i put the feeler in from the spring side instead of the spark side so my reading may have been off slightly.

Anyway after i adjusted it the vacuum was great! My idle still wanders for some reason, and the idle sounds something like this:


VRRRRRRRRR pup VRRRRRRRRR pup pup VRR pup VRRRRRRRRRRRRRR

it has these sligh hickups in it- not sure if its becuase it was tuned on the tight setting and now the tune is off cause of the adjustment or becuase i adjusted it wrong? It sounds almost like a slight miss...

Ideas?

I am doing arp studs on thursday so i plan to readjust then...

 

retune for lidel and low end power may be needed. I have the same issue and the tuner said I need to retune.

 

man, same thing happened to me the other day, i had it too tight, redid them this morning, now it sounds and feels great

 

its probably your timing. since you were running low vaccum your tuner adjusted the timing to where the engine liked it probably "retarted" cmopared to a motor with better vaccum . Now that you have better vaccum you may want to try adding timing at idle. around 28 degrees past TDC at idle might work. Then again i could be totaly wrong in your situation.

 

import thats a good idea i asked my tuner what he did and if he did that ill see what he says...


any other ideas?
