What is the correct plug gap, firing order, and timing for a 1999 dodge ram 1500 5.2L. trying to do a tune up after mechanic screwed me for $2,000.
You will find the spark plug gap and timing specifications listed on the vehicles emission label under the hood, and those specifications are the ones to be used on that vehicle and engine for that year, and no other specifications should ever take precedence over the specifications listed on the vehicles emission control label. Here is the firing order diagram for that engine, let me know if you require any further assistance, and I an curious as to how you got taken for $2,000.
Also, if the emission label says that the ignition timing is not adjustable, then the ignition timing is "static" and when the engine is at top dead center the ignition rotor should be pointing to a #1 position marker that is either on the distributor housing or on the hall-effect pick-up coil/ignition module under the distributor cap (see image) and if the position of the distributor has not been changed then there should be no need to set the timing.
Ignition Module. (located under the distributor cap)
