careful.....you can get in a heap o' hurt pokin' yer noggin' where it don't belong.
BTW, in the brief three views of the harmonic balancer in his vid, it looks to be turnin' pretty smooth. No wobble or anything.....

Google doesn't know what noggin pokin is. Therefore it doesn't exist in the known universe outside of Arizona.
Which everyone knows is in the southwestern US, not the south. Heck, Arizona doesn't even observe DST.
Except for the Navajo nation, which does.

Ok, so I'm gonna replace my distributor cap, rotor, and plug wires.
Wires:http://m.napaonline.com/parts/PartsD...404_0065774258
Rotor:http://m.oreillyauto.com/mt/www.orei...0413&ppt=C0334
Cap:http://m.oreillyauto.com/mt/www.orei...0413&ppt=C0334
Are those good options?

So guys, I got to thinking, could my coil be bad? The spark coming from my wires is tiny and it's not "blue and snappy," like someone else mentioned.

Ok. So I went and got my battery checked, just so I could rule it out, it wasn't it.
Tested the spark coming from the coil, it's not "blue and snappy," it's "sluggish and yellow."
Cleaned up the contacts on the coil and ICM, didn't change anything.
Oh, forgot to mention, it starts but won't run for more than a minute.

I'm going to test the coil and ICM to see if they're good or not. Then I think, the fuel pressure regulator and vacuum lines are next to be checked.
All that sound good to ANYONE on the forum?

Please don't take my post as being rude but I think you're missing the point of this forum. People want to see what you have done to fix the problem. Many of your posts are "What should I check" and "I haven't done that yet" or "I might do this" or "I'm gonna replace my distributor cap". What do you want people to reply to that type of post?
There are literally hundreds of posts on this forum that you can search and find people who have reported similar problems to what you have. When I have a problem, I search through the posts where people have reported a similar problem and see what they did and then I DO WHAT THEY DID and report back to the forum.
You need to be systematic and rule out the obvious. If you go through Cruiser's tips first, that will rule out the more basic issues like TPS, CPS, sensors, grounds etc. Then people will get more into putting out suggestions.
Please don't criticize posters either. Everyone is on here to help-No one is getting paid for advice. Try asking a mechanic what he thinks is wrong and he'll tell you to bring it in the shop and charge you $75/hr to "noggin poke"!
Good luck.
