I dont know if everyone elses car does this, but if I hold the car at a steady 1500RPMs you can hear the car missing maybe 1-2 times per second.
Get to 3K and it totally goes away....but heck my sisters car had a bad valve and was missing BAD at idle, but anything past 3500 and the engine sounded great.
Problem is that I cant tell if its missing at idle (re cams). Also in 5th gear at a steady pace @ 1500RPMs you can feel the car slightly jerking and hear the engine missing a bit. No engine light or anything....and its been that way since I can remember . Definatly since the cams though.
It would ONLY go away when I put brand new plugs in....and only for about a day and then the miss from 1100-2800RPMs (no load) is back. The low RPM (1000-1500) bucking issue that I (and alot of us cam guys) have could be a result of this miss.
Also, when we pulled my old LTs off for the turbo install...I think it was cylinder # 6 (drivers side 2nd to the front) ....I noticed that exhaust port was noticably different from all the others. It was CLEAN...like almost bare aluminum/white looking. No black stuff at all in the inside that you could wipe off like the other exhaust ports....whipe your finger in it and you get nothing, all the others gave you a black finger.
What would cause this? And all the plugs looked about even.
Thanks for any and all comments!
