Rough Engine When it is Cold


Sounds like the intake gaskets are sucking air when cold. When it warms up then they expand and take up the space and no longer **** air. You can test the theory by spraying a little water on the intake while it's running if it starts missing even more then that is most likly the problem. It's not a hard job to do, but if you do not have wobble sockets then it will be a little more diffacult.

But if they want 600 bucks to do plugs and wires then you need to find another shop to work on your tahoe! That's alot of money for something that only takes a few minutes to do, and the parts shouldn't be much more than 150-200 on the high side!

Car starts and runs fine until it heats up then it runs rough


Check spark plugs. The back pressure may be causing one or two to fail to spark and ignite the fuel mixture. While at it go out at night and start the vehicle and watch the spark plug wires for sparking to ground. If you see a spark form a spark plug wire change all spark plug wires.

Running rough and wants to die


Have the fuel pressure at the fuel rail checked. If you just want to throw parts at it: Fuel filter by the tank first. Fuel pressure regulator next. Order of ascending expense and likely hood. Does the fuel pump hum louder lately? The fuel pump may be on it's way out. It's not getting enough fuel to do anything but idle. Why that is takes some investigation. Somebody like Auto Zone may check your fuel pressure. If the fuel pressure is good, bad spark plug wires are the next guess. Lift the hood and run the engine in the dark (take the light bulb under the hood out if it still works to do this) If you see little lightening bolts traveling over the engine you need new plug wires. If the fuel pressure is good, the wires are good, change the spark plugs. Good Luck!

Rough


if it seems like it's misfiring... it seems to be the time of year you need to put a bottle or two of gas line antifreeze in our tank.

Runs rough and vibrates when idling


make sure the firing order is ok, that means every plug wire belongs to a specific spark plug and can't be swap to another
if the do not help then reinstall the old distribuitor cap and see if that cures the problem i have seen some aftermarket caps arking internally
also doble check spark plug for loose and retie
