Sadly this as it happened to me yesterday after I took my son to school!! :(
The whole of car will shake and the engine will rattle (open your bonnet and you will see it shake violently all over the place) also your engine will be very noisy, it will struggle up a hill or any slight incline and will not go over the speed of 25mph no matter how much you press the accelerator!
*REMEMBER* when replacing ignition coils make sure you replace it's pair!
for example
number 1 went so you need to replace number 4
number 2 you'll have to replace number 3
with mine number 4 went so I had to replace number 1 too and it's possible that 2 and 3 are going to follow :(
***I believe the previous answer was referring to spark plugs, not sure.
But I recently had to replace the ignition coil in my 92 Chevy Blazer. It really didn't give any signs of failure except that now and again the vehicle would shut off and take a few minutes to restart. I just bought the truck about 3 weeks ago and am still workin on it as there are a few things that are still not right, for example when i got it none of the vacuum hoses were hooked up.
Anyway, back to your question...the day my ignition coil went out and left me stranded I was lucky to have a Haynes repair manual in the truck with me. So after 30 mins of doodling under the hood I decided to check the coil pack. The Haynes manual gives a walk through for checking your ignition coil. Besides the few tools required to remove the coil you will need an ohm meter. There are 4 different test that can be performed with a meter. I was also lucky to have a meter with me and an Advance Auto a block away. $28.00 and 20 mins later, I had it reinstalled and haven't had any issues with the truck not starting.
*Tip: if you have to replace the ignition coil, and if it's like mine- the replacement will not come with a mounting bracket. You will have to reuse the one off the original. The new one will come with small bolts though. The original mounting bracket is usually fixed onto the coil pack via 2 pins that are pressed on. I simply used a sturdy screwdriver and hammer to break the head of the pins off and it will slide free.
Hope that helped.
