I have replaced the spark plug and wires, which has lifetime warranty.

Bosch Platinum 2 spark plugs and Duralast wires. Saved $200 than let mechanic do it.

Now the shaking problem of the car seems gone. We had P0304 error code which means #4 cylinder misfire. It did not go back to normal once we replaced it. But after we fasten/enforced both end of the wires, the problem seems gone so far. I suspect it is contact problem, and replacement of spark plug and wire might not be needed.

The speedometer still jumps, but not as often or bad. I suspect that misfire worsen the speedometer problem, although they seem unrelated.

I replaced the plugs and wires also, about a day after that, the car threw a CEL on and started to shake even worse.. Turns out the coil was cracked... Replaced it, and the car runs perfect now, no more jerking of the speedometer or bucking of the car.

i had the same problem. its prolly your speed sensor malfunctioning. my car did the same thing. have someone replace it and it should take care of it. your speedo and tach and trip run off the speed sensor which is part of the tranny so when your speedo jumps around it makes the car feel like its shaking and what not.

Mine did about the exact same thing. Here's my old thread.

And FWIW, it was the engine grounds. Good luck!

Problem solved

I think u might be having a problem with ur Mass Air Flow sensor aka MAF sensor my 94 tbird had the same problem but the only diff was that the rpm and the Speedo would jump I bought 2 cats new wires spark plugs and coil pack and all to find out that the maf was the problem wich was worth on 8 buckaroos at AutoZone vs 400 for the cats and stuff
