shuddering at the lights, why????

[tacoma]

89 Blazer with a 700r4: shudders at lights, MUCH less so in N, so I'm guessing somehow trans-related. I haven't checked to see what it does in D, so no info on that.

Shakes pretty good. What might be causing this? I am hoping you'll all jump right in and say "ooooohhh yeah, that's the 89 Blazer Shake, smack the glovebox with a #2 Phillips and you're good to go" BUT I DOUBT THAT"S GONNA DO IT!!!

thanks in advance, fellers, yer a swell bunch.

sounds like it may be a bad tranny mount to me....

Umm, could be that the idle speed is low, or may you just need a tuneup as the idle is rough?

Sure, could be motor mounts or tranny mounts ... but check the basics first. Plugs and wires, ignition parts as appropriate for your year? (cap, rotor, whatever.)

right now I"m leaning towards the tranny mount myself, as the vibrations almost stop in neutral.

find out in a little bit, I"m going out to try and find the cause!!

edit: cap, wires, rotor, coil, all new and right parts.
