Hi,

I'm Ben and -- hopefully -- I can provide some meaningful assistance.

I recommend a diagnostic scan to confirm my diagnosis of a malfunctioning coil(s).

How to Test and Replace Ignition Coil on BMW 3 Series

The following procedures apply for BMW 3 series (6-cylinders engine) 1992 - 1998 model years. To Test and Replace the Ignition Coil, do the following:

1. Remove plastic engine covers from top of engine by prying off nut covers and removing cover mounting nuts.
2. Disconnect harness connector from coil. Connect multimeter between terminal 15 (+) in connector and ground. (use a digital multimeter for the following test). See Fig.1. below BMW 3 series coil harness
3. Turn ignition on and check for battery voltage. If battery voltage is not present, check wire between terminal 15 and ignition switch. The wiring to terminal 15 (+) of the coil (via the ignition switch) is not fuse protected. Use care when testing this circuit.
4. Turn ignition off.
5. Use a multimeter to test coil primary resistance at coil terminals. (primary coil terminals: 1 (-) and 15 (+), primary coil resistance: 0.4-0 .8 ohms; secondary coil terminal and resistance: NA).
6. Remove coil and inspect coil housing for hairline cracks or leaking casting material . A leaky ignition coil may indicate a faulty engine control module (ECM). Check ECM before installing a new coil.
7. When replacing ignition coils, ensure that the replacement coil(s) are from the same manufacturer containing the same part code numbers. If individual coils with the correct specifications are not available, all coils should be replaced.

Check engine light on ? Code's ? What engine ? 2.3 l 4cylinder or 3.ol v-6 This vehicle has coil on plug ignition system , not coil packs ! a coil per cylinder . If new coils an still has no spark , has no B+ voltage to the coil or the PCM isn't controlling them . Without testing i'd only be guessing as to the problem .If the repair shop you had it to can only say it had to be the coils , I'd find another shop to take it to !
Autolite Coil on Plug Ignition troubleshooting

I believe the Mazda V6 is the same as my 2002 Escape and uses individual coil-over-plugs or COPs. Each spark plug has it's own coil.
I've had an engine light twice, and needed to replace coils. I finally replaced them all. They are available at Ford, car parts stores like AutoZone, or I bought my full set of 6 coils on Ebay.
Autozone coils, for example are about $70/coil.
One of the difficulties with replaceing the coils, is that the 3 coils on the "back" of the engine are covered by the intake manifold. The manifold needs to be removed to get to them. You'll need the manifold gasket set, which costs less than $15.
The coils themselves are easy to replace. Unplug the 2 wire connector, unscrew one bolt (using 8mm socket?), and pull the coil up and off the plug.
I recommend replacing all the coils, and also replace the plugs while you're in there. Use OEM plugs; probably Motorcraft. (If the original plugs lasted 100,000+ miles, why would you experiment with something else?)
Here's a picture of one coil:

You have 8 coil pack's, to remove undo coil harness then remove small 8 mm bolt slide coil pack out and replace with new one, if replace all do same with all, you will have to work it around fuel rail, but I have never heard of all coil pack's going bad.

check timing sensor

hi i have a coupe 1994 have same prob told by audi to replace the distributor as was common failt on audi's i have replaced new leads ,coil ,dissy cap, and arm ,still the same awaiting on distributor to see if this works hope this helps

check the signal voltage going to afected coil harness, should be geting 12v. if its 0, the you may have a broken wire or pin on jack for that coil assembly
