I've been having intermittent problems with my car bucking back and forth while driving at normal driving speed (40-60kph). It has happened to me twice in the last two week and is very noticeable. After fairly short, erratic bursts of power loss and car bucking it subsides and my car drives normally.
Searching here, people here mentioned the possibility that it's the transfer case. I had my mechanic who is familiar with dsm's checked it just a couple weeks ago and found no issue (no fluid leak from the yoke). Should I double check the fluid level?
On another site people mention that it could be a coil pack, spark plug, spark plug wire, or injector problem. How do I go about narrowing it down? All I have is a logger and keydiver chip that shows me knock.
