I need to replace an ignition coil. I had a P0305, swapped coil with #4 and now I get P0304.

I have already cleaned the TB and MAF sensor. New AC plugs last year and the plugs looked fine when I swapped the coils.

I'm pretty sure these are the original coils. It's a 2006 with 175,000. Should I replace all 5 or just the bad one?

What are you replacing these with? The ACDelco are very expensive and I see some cheap one's on Amazon for a whole lot less. I'm looking at ENA set of 5 for $72.99. Or I can get one PT Auto Warehouse brand for $24.50.

Any recommendations?

Thanks!

 

I would do the AC Delco coil and I would replace the one that is bad. The other four could go for years without having any problem, or they could puke tomorrow? I would never skimp on ignition parts.

My Grandfather always liked to say: start with the easy stuff, and never fix what ain't broke.

Good luck.

 

Yeah I found an ACDelco for $51 and I'll get it. The first couple of searches they showed up for over $100.

Thanks!

 

AC Delco coil on Rockauto is under $26
