have a 95 c1500 engine 305, i replaced the plugs,wires,rotor button,and cap, valve cover gaskets,..
i am also experincing the same issue, but it happens at 50 mph it seems when i hit 50mph and try to stay constant at that speed the motor seems to bogg down and start to shake,it also stops if i let off the gas or speed up just a tad... i have bran spakin new tires, and i know for a fact its my engine that vibrate/shakes..... not the tires or any veriation.
also, my truck does Not smoke grey or whit.. and does not throw any codes but yet my truck reeks of gas, i have replaced hoses to pcv valve and to the egr soildnoid.. and it gets about 9 miles to a gallon any solutions?

9MPG...ouch
I got right at 20.8mpg on our 700 mile trip, no power issues at all - just got the random shakes! I tried to offer the truck a beer to get over the detox but didnt help

ok how time flies...just got back from the dealership and took my service guy on a ride. he hooked up the engine diagnostics when we drove so he could monitor the TQ converter. sure enough I was able to get it to shake when driving around 45mph being very easy on the throttle and when we started going up a hill the truck would shake. so basically when under light load it will shake. it is easy to make it happen at this speed because that is the speed the converter kicks in. anyway, he would push a button and remove all TQ management and lock it up and the shaking would go away immediately. therefore narrowed it right down
on a side note I can imagine how much more fun these things would be to drive removing or limiting the TQ management...with it removed the shifting was so nice and firm
they are going to replace the converter for free tomorrow so that is good news especially since it is technically past the 5 year PT warranty.
I will update again when I get it back tomorrrow evening

Believe it or not I always try have my vehicle washed, vacuumed and tidied up before I take it in for servicing. The hope is that the tech(s) will see that I take care of my vehicle and will in turn, take care to keep it that way.
I do think that a complementary wash goes a long way too for building customer loyalties, its a simple and inexpensive task that makes a customer feel like they got something extra for free....

ya I agree - too bad my wife and 3 year old daughter use the Tahoe for a storage "area" most of the time. the service guy laughed when he got in cause I had to throw crap into the back for a few minutes.
but that is another reason I like to keep the engine clean. at least they cant clutter that part up!
