Anyone know any pages where I can get a step by step instruction on replacing IAC and/or spark plugs on my '86 Z28? I plan on doing the spark plug job myself (I know, first time will take 6-8 hours ) but I could use the experience I guess. Anyone have any help?

 

Always find that jacking the car up and taking the front wheels off helps. You'll be working from the top and the bottom and you'll need a few attachments from your socket set. Patience is the key and make sure there are no women and children in earshot when you're doing it Good luck

 

all i can say is www.helminc.com . They sell the official dealer service manual for our cars it is over 3000 pages (thicker then a lot of phone books). Basically it tells you how to disassemble and reasseble everything on your car from how to take out the drive shaft, to how to completly dissassemble and reassemble your a/c compressor. It tells you the tq specs for ever nut and bolt on your car, and it is the first thing anyone with a camaro should buy. Mine cost me 90 bucks + S&H which while it is expensive (everythings expensive when youre 17 ) i swear it has paid for its self 100 fold. This would give you pretty much all of the info you will need for removing any piece on your car that you ever will. It also has fairly detailed (as detailed as youre ever going to get from anywhere) pictures of everything too.

 

Brit Iroc: lmao, I don't know we'll see




This is what I was looking for, a complete guide for the "Camaro Gearhead"

Thanks man, I'm going to check it out

 

i just bought one for my 90 camaro off e-bay for $50. the new ones are $90, so i would look there first. just go under ebay motors, than to manuals and search.
i just did a quick search, and couldnt find one on auction right now, just wait and there should be one

 

Dont sweat the spark plugs man. Im 17 and its not that hard. You are probably worried about screwing something up. I was like that at first but its all good now It will take some time since its your first time but like Brit Iroc said, patience is the key good luck and have fun!

 

The only thing stopping me now, other than time, is the fact I'm doing it myself with little experience in engine work

Either I'm putting these spark plugs in and everything will work fine, or I will end up putting a hamster wheel out of desperation in the engine bay and pray for the best because I royally ****ed up

 

spark plugs are simple put spark plug socket on, loosen, pull out. When you put the new plugs in theres a couple things to keep in mind. First of all they dont need to be crazy tight the general rule is do them finger tight then give it 3/4 to a full turn and they should be in fine. If you drop a spark plug assume it is broken, for the dollar fifty they cost to replace its not worth the risk of putting a bad plug in because they are ceramic and one drop is more then enough to wreck one. Make sure you buy a spark plug gapper (they cost like a buck) and gap the plugs properly. I forget the correct gap off hand im sure someone will chime in with it. Thats pretty much it dont expect it to take 6-8 hours it should take 2 max and that was my first time ever doing it with slp headers that sit real close to the engine. Also if you have the smog equipment the two plugs on the passenger side closest to the interior (the 6 and 8 plugs) you will be forced to get at them from underneath the car. I think thats everything if i remember anything else ill post it. best of luck to ya.

 

Thanks for the info Doug!

Yeah I heard about the two plugs you have to reach from underneath to get

No problem though...I think the gap is 0.035 but I could be wrong, that's what I heard though

 

yeah thats it, just been a little bit if i looked at my gapper i could have probably had it come back to mind. Yeah man no problem just basics people told me before i went and started toying around. Once you start to get into it if you have a little bit of a guiding hand its not hard to do stuff, this summer i had to tear apart my tpi twice and it just gets easier and easier the more i get into it ....Just dont give up ive gotten to the wrench throwing point a couple times. Replacing engine mounts is something id never like to do again. 5 hours for 1 mount that was entertaining....took it to a mechanic for the other mount and paid couldnt deal with it. Lol isnt that inspiring. Its all good in the end though because so much of your quite literally blood and sweat go into the car and when its all finished and just purrs its fantastic. Thats what its all about.

 

If I were to replace the IAC, I would take out the entire TB and clean it up good with brake cleaner. Do the TB coolant bypass and clean out the IAC housing with a fresh gasket. Screw in the IAC and start the car. If you have a scantool, drive it for a bit and when it is warm, let it idle. Attach scantool and check for IAC counts. It should be between 20 and 30. Higher than 30 means you need to turn the Throttle Blade screw clockwise till it gets to the range. Lower means you need to back the screw out.

 

Thanks for the advice on the IAC Aklim!
I forgot all about it man. I'm thinking about investing in a 1986 Camaro service manual for 75 bucks, over 3000 pages of good ****

 

Start with the basics. Go to a Goodwill or St Vinnies or used book store where they have Chilton's at a discount. Grow up a little with that before you go spend big bucks on a GM tech manual.

 

I saw one on ebay for $10 bucks new, maybe I should invest in that? I saw one a while ago at the store too but I couldn't look inside, it had the wrapping..
