Firing order is 1-6-5-4-3-2. Distributor cap should be numbered. Number one cylinder is front on driver's side (3 and 5 follow on same side). Number 2 is front on passenger's side (followed by 4 and 6).

Changed the spark plugs and wires, now my engine makes a knocking sound. Why?


you may have the firing order wrong. best practice is to replace one at a time so not to get wires crossed with the wrong spark plug. your local parts store or the dealership can provide you with a print out of the firing order

The engine misfires when accelerating


Depending on your Grand Marquis's mileage...it sounds like plug wires and plugs...(worn out) and or engine timing/firing order? If plug wires recently changed...the spark plug wires are in the wrong firing order...confirm the firing order from your local parts store by phone...and retrace each one...always start with #1 cylinder...hope this helps.

I changed my spark plug wires and possibly have them connected wrong. Is there a schematic that I might follow in order to ensure they are connected correctly?


FIRING ORDERS NOTE: To avoid confusion, remove and tag the spark plug wires one at a time, for replacement. If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired. Fig. 1: 1988-95 4.3L Engines Firing Order: 1-6-5-4-3-2 Distributor Rotation: Clockwise 91022g01.gif
Fig. 2: 1996-98 4.3L Engines Firing Order: 1-6-5-4-3-2 Distributor Rotation: Clockwise 91022g02.gif
Fig. 3: 1988-95 5.7L and 7.4L Engines Firing Order: 1-8-4-3-6-5-7-2 Distributor Rotation: Clockwise 91022g03.gif

Change spark plugs and wires not truck wont start. could firing order be wrong!


You could have mixed up the order of the spark plug cables causing the firing order to be wrong. What is the exact year, make, model, and engine size of your truck?

I think my spark plugs are in wrong, whats the firing order?


firing order is 1-4-2-5-3-6

Asyou face the front of the car,
Cylinders are numbered like this:
1 2 3
4 5 6
(#1 is on the passenger side near the firewall.)

They should be Coil-over-plug.... no plug wires.
I'm curious, how do you get the firing order wrong?

Replaced the plug wires, and now I have a slight miss at idle ?


Possibly a bad plug wire in the new set ..it happens.

Or you may have got two or more wires in the wrong firing order
