I was wondering how often you can expect coil packs to go out? I purchased a new-to-me 1999 Land Cruiser in late December. Since then I've had to replace 4 coil packs. So with 4 packs replaced in 5 months I'm wondering if this seems unusual. Should I just plan on replacing the remaining 4 right away? The truck has 156,000 miles on it so I expect I have some things to change out but this just seemed a bit odd based on posts I've read on here. I see people with 1 or 2 going out but nothing about them going out frequently. When I changed the 3rd coil pack I went ahead and replaced all of the plugs with new Denso plugs because I didn't know how old the plugs were in there. Guess that didn't work because a few weeks later it threw another code for cylinder #1. Replaced that yesterday and she's running great again.
Thanks to all you who keep this board going. I've found it to be a wealth of information. Pretty much any issue I've run into I have been able to find something related on this board. I know know a lot of other things to look out for and I'm also making my list of future upgrades too. I know as a newbie I need to post some pics. She's still got her skirt on though - haven't been able to buy some sliders because I'm spending all my money on coil packs and plugs I can't take the running boards off just yet because i have a vertically challenged wife and a couple of kids that use them on a regular basis.
