What year?
Years up to 2000, you need to look at rotor arm, cap and leads.
All years check plugs and clean the IACV.

air leak?

Make sure the IACV is clean and the wiring to it is cable tied to the valve body.
I've come across some bad wiring in the main harness to the engine before now too.
You could also have a coil down, effectively letting the engine run on 2 cylinders. Is the MIL on?

Do a compression test as well to eliminate mechanical problems.

Had it plugged in yet? faults don't always trigger the mil light

tonytherunner · Jul 18, 2014

The engine starts fine, MIL is not on her to-check IACV again, the law was dirty but I did not bother to clean it perfectly
.....counts and the quality of petrol?, I noticed better gas decreases vibrations but not very much
....vibrations start after the engine reaches Optimum functioning temperature

@freelance
air leak?

where to lose???....is there any method to check

thanks for answers

The throttle pot has been known to cause issues.
Does it drive ok? Or does it hesitate?
My V6 is messing around at the moment, I suspect it's the fuel pump.

I changed the fuel pump, especially at the start gave misfires, 3-cylinder now go shoot well without hesitation
.....vibration at idle only appears when you press the throttle disappears
