I dont know what the heck to call it...I'm on the brake waiting for a light and I get a jerk....sometimes, sometimes I step on the gas, and it bogs-stumbles, idle drops a bit,...wierd. I have an auto tranny, use Amsoil (changed it last month) did the plugs less than a year ago....oh yeah, 2.7. Any ideas? Also ran BG44K a month before I changed the oil..got about 120k on the clock. Thanks.

 

Brian,

My guess is a loose vacuum hose. When I installed my spark plugs, I had to remove a few hoses and specifically, the hose running to my PCV. Well I didnt plug one of the hoses back (forget which one), but everytime i came to a stop, my 4runner "lurched" forward.

After poking around, it was pretty obvious that a hose was unattached and just dangling there. Plugged it right back in and no lurching.

Thanks Bob. I'll go look now...man I hope it's that easy!
Dang it...every hose is solid! Any other ideas? Thanks.
