Probably not the plugs if they look good but more likely a problem injectors which is the case in most misfires

SOURCE: I have a 97 pontiac sunfire 2.4l it has no power

If the liquid smells like antifreeze its a blown headgasket or cracked head, if it smells like gas it could even be a stuck injector or a bad fuel pressure regulator. I would like to say it is uncommon, but its not that uncommon for a quad motor to have a headgasket issue sometime.

firewall. and on drivers side # 2 # 4 # 6 with #2 closest to radiator
or front of motor, and #4 in middle, and #6 at the end by firewall.

How do I no if i have a bad coil on my 2004 Bonneville GXP 4.6 Northstar


if you have multiple coils then there will be a regular misfire on a particular cylinder. If you have sets of coils then the coil that handles a set of plugs will misfire on those plugs. If you have one coil to do the lot then indicators are engine will not start, coil lead will show a weak orange spark when sparked to metal, engine will start fine and run for a period of time before the coil overheats and starts to break down ( misfiring), coil is very hot to the touch (burning ) after minutes of operation.

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.

I replaced my spark plug wires on my 1996 chevy truck. may have crossed one,need a diagram from the spark plugs to the distributer cap.


Since you didn't state whether it is a V6 or V8, I'll give you both.

V6 -4.3Liter
Firing Order is 1-6-5-4-3-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap, faces the front of the engine.

->Drivers side, spark plug order in engine, starting from the Front going back:
1-3-5
->Passenger side, spark plug order in engine,
starting from the Front going back:
2-4-6

If it's Electronic, the distributor cap has a Left side, (Drivers side), and a Right side, (Passenger side)
Starting from the Front, going back on the Left side,
3-1-5
Starting from the Front going back on the Right side,
2-4-6

V8-5.0, 5.7, and 7.4Liter
Firing Order is 1-8-4-3-6-5-7-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap,
faces Front, towards the Drivers side.

Electronic distributor cap has two sides. Drivers, (Left), side and Passenger, (Right), side.
Starting from Front going back on Drivers side,
1-7-3-5
Starting from Front going back on Passenger side,
8-2-4-6

Spark plug order in engine, starting from Front going back, Drivers side:
1-3-5-7
