I need to know where the plug wires go.from spark plug to distibuter cap on a 1986 4.1 coupe deville(cad.)


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: GM (Cadillac) 250 (4.1L) V8 GM (Cadillac) 273 (4.5L) V8 Engine firing order: 1-8-4-3-6-5-7-2 Distributor rotation: counterclockwise 85872009.gif Fig. 2: GM (Oldsmobile) 307 (5.0L) V8 GM (Oldsmobile) 350 (5.7L) V8 w/EFI Engine firing order: 1-8-4-3-6-5-7-2 Distributor rotation: counterclockwise 85872009.gif Fig. 3: GM (Buick) 252 (4.1L) V6 Engine firing order: 1-6-5-4-3-2 Distributor rotation: clockwise 85872010.gif Fig. 4: GM (Cadillac) 368, 425, 472, 500 V8 Engine firing order: 1-5-6-3-4-2-7-8 Distributor rotation: clockwise 85872011.gif Fig. 5: GM (Cadillac) 429 V8 Engine firing order: 1-8-7-2-6-5-4-3 Distributor rotation: clockwise 85872012.gif prev.gif next.gif

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?

1985 5.7 corvette backfires when cold not as much at operating temp also wont idle , checked timming it is set wires are not cross replaced the module in the distributer


did you set timing properly ? you have to unplug the timing wire connector by the distributor its a tan and black wire with a black plug in it then set the timing at 6 degrees in park for a manual trans 6 degrees in drive with emergency brake on the firing order is 18436572 the left of the square power connector on the distributor cap is no 1 going to the left clockwise follow the wires to each plug carefully and make sure they are not mixed up it happens . driver side front is plug # 1 passenger front is plug # 2 driver side second from front is plug # 3 passenger side second from front is plug # 4 and so on also check the distributor cap and rotor for any signs of corrosion p.s. the # 6 and 8 wires are the ones usually mixed up after you set the timing the computer has to go through a re-learn mode for a few minutes so idle the car for a few minutes then drive it at about 20-30 percent throttle and let the trans shift into high gear for automatics manual same thing but shift it yourself after 5-10 minutes it should be fine

What is the proper plug wire sequence on the ditributor cap for a 1998 Dodge Dakota 4 cilinder?


For all Dodge 4 cylinder engines, the firing order is 1-3-4-2
All dodge distributors rotate clockwise.
Standing on passenger side number 1 is at bottom left or 7:00 o clock.
going clockwise number 3 plug wire is next then number 4 then last one is number 2 wire.
plug wire number 1 is 7:00 o clock
plug wire number 3 is 11:00 o clock
plug wire 4 is 1:00 o clock
Plug wire number 2 is 5:00 o clock

Change plugs and wire and engine will not acclerate. This is a built 350 short block chevy with pro charger.


350 Chevy engine in what? 1990 Corvette? Who built it, did you?

Sounds as though you have plug wires wrong.
Firing order is 1-8-4-3-6-5-7-2

Distributor Ignition System:
Distributor rotates Clockwise. (Rotor)
Find Number 1 tower on distributor cap, go Clockwise with Firing Order.

Distributorless Ignition System:
VIEWING the engine from the Front of the car.

Spark plug wire connections along the back, starting from Left side going to Right side;
2-3-7-4

Spark plug wire connection towards the Front of the engine;
6-1-5-8

(To guess I would say you have 5 and 7 wires switched)

Left side cylinder order is 1-3-5-7, going from front to back.
Drivers side is Left side.
Right side cylinder order is 2-4-6-8, going from front to back.
