Its actually unvented. Unvented 93-94, Vented 95-97

Check Shoebox's webpage for Dal's number or Jason Cromer's number. Its probably going to cost less from Dal since he's closer Akron, OH, than Jason in Florida.

Has a lot of good stuff on there. Helped me more than once.

I still say change the plugs first. Don't even start thinking about buying an opti until you change the plugs.

 

Yea, do plugs and wires first. Thats what I did before I gave up and found it was my opti.

Have someone local look at it, I know I've seen lots of Chicago guys on the boards. It's SpeedInc around there too?

well i did plugs today and it took my friend and I 45min while each of us did the side of the motor. my car doesn't shake at all when i idle now but i still miss up top. i am going to do wires next week and if that doesn't do it i am going to have my mechanic tell me whats wrong and see if i can fix it. thanks for all the helpful replies.

 

Whatever shops you went to NEVER GO THERE AGAIN. They screwed you royally.

 

This may be a stupid question, but Did you change the coil wire as well?

 

The nice thing about misses, is you can always fix them yourself. Wires and ignition coil would be my next step.

 

For God's sake dont go back to "My Mechanic" cause "My Mechanic" is really trying to bend you over, dropped soap prison style.

Seriously contact a LT1 guy locally and have him help diagnose the problem, if not your just going to **** you money away.

i had actually planned to do wires next weekend but yes i am going to do them. how much is a coil wire and is it hard to replace?

 

A coil wire came in my MSD LT1 plug wire kit. So it should be included.

-Dustin-

 

Yep, my Moroso wires came with it as well. It comes with all the kits.


And it's the easiest wire to plug.

 

yep ur right. i got nine wires when i bought my set. i just hope this fixes my missfiring problem. although it did get much better when i did my plugs, i learned my plugs had never been replaced even though he said he did them, they were 20000ths of an inch too big. after my new plugs my car stopped shaking when idling but still missfires. my money is on the optispark

 

The 20 thousands of an inch means it was running a little colder than it should have.

Also, were there 9 wires? Or 8 wires with a plug looking coil?

I think I might add this to my diagnoses page I'm working on.

 

Yeah the extremely short (and un-numbered) 9th wire is the coil wire.

 

Ok, just making sure since the package for the van had an extra spare wire.
