Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
HelloCustomer You've ruled out spark plugs and ignition wires. Next step. check for spark at that ignition wire. Then your next step, swap coil packs so the coil pack for cylinder 5 is somewhere else. See if the misfire moves. Finally suspect a faulty intake manifold gasket or fuel injector. These manifold gaskets are horrible for leaks. Spray some carb cleaner around that #5 cylinder mating surface and see if the engine responds. Fuel injectors are very common for plugging up and not allowing enough fuel to enter the engine. I hope this helps. As far as for cost, they vary tremendously between the repairs. See if you can rule some things out and then we can focus on the remainders.
Your JA Expert,
Just so you can get a better idea as to who you are speaking to...i am a single mom without a whole lot of funds for repair. Now that we got that out of the way... I am new to learning about my engine. If the coil pack for #5 was bad, wouldn't #2 misfire as well (since it fires on the same pack)? Further, a guy friend of mine tested the spark on #5 and got an orange glow (of course, that was before replacing the plug).
Start with swapping the coil packs and checking compression, also while you or your friend is at it, spary the carb cleaner around the mating surface of the intake manifold. Let me know what you find, and we'll go further.
I will do. Thank you so much Ivan, I am glad to have found this site. More importantly, you were very easy to understand and you also gave some insight on troubleshooting I can do on my own before having to ultimately take it in. After I/we try your suggestions is there a way I can contact you rather than having to go throught the whole explanation again or do i just have to re-explain and reask my question in the future? Thanks again!
This link will stay open, just add to it and I'll get it. I'll be here when you need me.
