Troubleshooting then replacing various ignition components until engine is repaired: plugs, plug boots, ignition controller, ignition coil assembly. Includes how to and pricing, and hopefully a little entertaining. This was for a 2003 oldsmobile Alero, but this engine is found in lots of GM cars.

Between the module and the coil pack there is a small connector that you may have missed when you tried to put the old module back on , that's why it didn't run it happened to me
I'm inn this exact senerio . I can't afford both and module and coil. I'm going for modue
Since you love to be a parts replacer put in new battery, engine and Transmission and injectors, Also replace the fuel filter and a new radio. Buy some polish and shine up the car.
I have the same problem with my 06 Chevy Cobalt 2.2 it run,s shitty vibrate,s motor gets loud and lose,s power then it will clear up and run great again for months and when you least expect it it'll run shitty again. No codes come up car has original 26000 miles on it bought New for 2nd vehicle.
Grandmas alero has 296k miles, all parts replaced by me and all eBay parts. First time I’m doing this gasket it on it, appreciate the video. I can watch this as I do it, I know it’s been a couple years but any chance you get anymore videos for this car, post it.
You didnt waste money everything you changed would have went bad anyway especially the ignition module its good you changed the coil and module together they are notorious for going out with these engines( ecotecs are somecof the worst engines built so if you keep this car be sure and stay on top of ALL the regular maintenance oil change etc. and they can be notorious for oil burn off so keep the oil and filter changed regularly also
You can test the original coil pack and ignition control module before swapping in new parts. First check the coil pack for continuity and resistance. A dud coil will show dead (primary) circuit for 2 cylinders (1 & 4 or 2 & 3). A dud (secondary ( high voltage)) coil lead will show one defective cylinder connection. If the coil pack is OK then the problem is with the ignition controller. You can test for pulses as the engine is cranked (again a pin for 2&3 and one for 1&4) center pin is hot. As in this case, often they fail together so replacing both is required.
Love the video especially the intermission so cute, if I may give a little advice always start your bolts by hand then use the driver especially when working on anything that has aluminum parts, could have been an even more expensive repair if cross threaded or stripped one of the bolts. Just some friendly advice from someone who learned that the hard way.
Great troubleshooting piece. I’m helping a lady fix her car with the same symptoms. I shared this video and tools with her. She fixed her ‘05 Malibu her self!
Thanks for your help and your daughters interlude.
