Need a Part Identified on a 2000 Camaro

[Pemolis]

I would look it up, but I have no clue what the name could possibly be.

My car's been jolting due to a power issue in the engine. I know for a fact that it has to do with the connection from the battery, to the actual spark plugs in the engine (thats alot, but I'll narrow it).

The wiring is good, I know that.

What I believe is the problem is that with these cards, there are 3 or so Coils inside the engine. These send the electricity from the wires, into the spark plugs. I know these are underperforming (probably one burned out, and the fuel isn't burning properly when the combustion happens).

What I need to know is what possibly those coils could be called. This is a V6. Any idea''s?

Are they the ignition coils?

2000 V6 would be a 3800. "Jolting" could be misfire, but it is hard to tell. Is the Check Engine or Service Engine Soon light on or has it been on?

I would do plugs and wires before replacing any of the three coil packs, though prolonged operation with a high-resistance wire will kill a coil pack.

I realize that you're probably wanting to do it yourself and keep the cost down, but I will suggest letting someone who knows this engine and ignition system have a look and do some preliminary testing. F-cars also aren't known for their easy engine accessability or their roomy engine compartments. You might be better off to do the plugs from underneath the car.

If you take a stab at this, use ACDelco plugs and wires. Trust me on this. Be sure to put silicone grease on the insides of the plug wire boots at both ends.

A "quick-and-dirty" test for ignition secondary leakage (holes in plug wires or secondary voltage arcing to ground rather than firing the plug): Fill a plastic spray bottle with water and LIGHTLY mist the plug wires and coil packs. Have a friend start the engine, put the car in gear with the brake FIRMLY applied, and raise the engine speed to 1000 RPM or so. This loads the ignition system by running the engine up against the brake. Don't do this for more than five seconds at a time so the trans doesn't overheat. Look under the hood while under load, look for sparks, and listen for snapping sounds. This works better at dusk or at night - sparks flying are more visible that way.

I will be doing the work with my Step Father and probably one of my uncles who owns a garage (so we'll have the tools). Both of them have done this before and from both theirs (and my judge) it probably is the coils. We've changed the spark plugs recently and that wasn't the issue.

Also we did hook the car up to a computer and the readout came back that the coils were underperforming. Some support for that theory is power spikes the car has from time to time (voltage meter drops 5 to 6 volts, then bounds back up). Also when reving the engine, under 2000 RPM the car jolts, once past it tends to level out.

We believe its the coils. though if we do them we'll probably do all the wiring also (car hit 70k).

Thanks for the link I have an idea what the heck they are called now.

This deals more with the primary and control side, but...
