If you havent done so already try replacing your oxygen sensors. There are 4 of them, the two in the front are the first that i would replace.

try rotating your tires from front to back, so as to eliminate the possibility of a broken belt in a tire. See if your shaking moves. Hope this helps.

Yes i would think so.These new vehicles are suppose to go 100,000 miles before it gets a tune-up and yours is there.I would like the sparkplugs are culprit.

While driving dwn the road i hve a bad shake in my steering wheel i have a 1999 gmc yukon


it sounds like the front tires need balancing.if you drive the truck slowly(creeping down the road at about 5mph)and lightly holding the steering wheel do you feel the steering wheel moving back and forth.this could indicate a bad belt in a tire where as a wheel imbalance won`t show up at this low of a speed,but a bad belt will.also have the front end checked for worn front end components and wheel bearings,this can cause a bad shake too.

When driving once you get up to 45 miles per hour starts to shake whats the problem ?


Not knowing where the shake is coming from, my guess would be to have your tire's check out, and go from there.

I would check to make sure you are getting spark to the plug itself. I would connect that cylinder wire to spark tester and check for spark. You may have a bad fuel injector for that cylinder.

Engine shakes only when it starts one it warms up


could ge a leaking injector flooding the engine at start up, or coolant getting into the combustion chamber, either intake or head gasket, do a pressure leakdown test on both fuel and coolant,

Hesitation / missing / car shakes


Hello;
The problem is most likely break down of the spark plug wires. The demands on the spark during acceleration and load destroy the wires as they age. I would start there. Hope this helps.
Thanks;
