Shakes or Wobbles problem
1994 Chevy Silverado V8 Four Wheel Drive Automatic
----------------------------------------------------------------
a few weeks ago my buddy and I changed out the plugs/wires/cap/rotor. and then after a week and some it feels like its misfiring when i was stopped at a drive thru. so i was assuming that one of the wires had come loose off the cap, but when i check everything is still tight. it has a really rough idle and when i press the gas it shakes too. the exhaust fumes smell different from the norm. all plugs are gapped correctly, firing order is also correct. dont know what could be wrong.

Check the idle air control valve/throttle position sensor/PCV and EGR valves-might also want to check out the fuel pressure.
