I just replaced my 02's and my plugs n wires. I still have a problem somewhere and I think its my opti. Im having some starting issues and a minor misfire. Im hoping it is my opti so its the last thing I have to replace. Anyways, wheres the cheapest place to get one at???? Thanks.

 

I bought a vented opti for less than $200 from Sam Taylor. P/N in the link.

Id call Autozone. Ha ha, no seriously, I think I heard on here that Autozone now sells a real cheap opti, like $120 or something like that, and it comes with a Lifetime guarantee.

I just got mine from Jason at Sam Taylor too. The whole unit not just cap and rotor for ~ $180 shipped.

 

Thanks guys. I will check into those places and see about the best deal.


One more thing. A bad opti can cause starting problems right? Sometimes my car deosnt wanna fire right up. Could this be opti related?

 

About 3 weeks ago I got it from Jason Cromer for $195 + shipping.

 

What were all of you symptoms of the bad opti you guys were experiencing???

 

jason only sells gm right, if so ill hafta call him

 

I recently read an article in gm high tech performance last month that ought to help you decide for sure if its your opti. I know this because my opti is basically gone and all the symptoms are hitting now. Here is a quote:

Is Your Opti-Spark Failing?

LT1 owners have dealt with the Opti-Spark distributor for 11 years now, but there is still much confusion regarding the causes and symptoms of a failing unit. Tapping into the PCM with a scan tool is a good way to start, but sometimes no codes will be set. Before diving into the Opti-Spark, be sure to verify that your grounds are good and the coil and wires are not the source of the problem, as they are much easier to change.

Symptoms:

* Car suddenly dies and won't restart
* Starts but immediately dies
* Extended cranking to start
* Rough idle
* Sputtering
* Backfiring
* Trouble reaching higher rpm
* Black smoke from exhaust
* Poor performance with car warmed up
* Weak plug wire spark
* Codes 16, 36, and 42 may be set

 

i've had bad opti for over 10,000 miles now i know i know i need to fix it

 

Changing my opti out helped so much.
I have a friend with a Bullitt mustang and I thought my car wasn,t pulling hard up top, well we raced friday nite and I let him get the jump just to see if I could catch him, No problem at all now.
He was like, I don,t know what your complainin about seems to pull good to me.

 

Well, I have about 5 of the symptoms listed above. I think I will be looking into a new opti very soon.

 

Hi all,

Advance Auto, or www.partsamerica.com has cap and rotor kit for repairing the opti. They are around $130. This fixes most all problems with the opti. You will need a torx socket to get into the opti. and it is small. I think it is either #6 or #8 torx socket, and most torx sets only go down to #10.
