Amen.



Kimmer- Waiting to see what you came up with as the culprit.

 

Ok, as you know the car ran great after the install but when I started it 2 hours later it ran like crap. For some background I have a quiklift and its always in the incline position thats where I park the vette. I checked everything twice to make sure all was connected, started it up and still ran like crap. I'm the kind of person that after a while I start to get POed so I backed out of the garage and took it for a drive putting the pedal to the floor. Surprise to me that after a while it started to smooth out more and more until it was running normal. My reserve tank warning went on then it all came together. The tank read over a quarter full when I took off but you know how inaccurate they are when they get low so I figure my fuel was much lower than I thought and after the first test drive I used more of it. When it was parked I believe all the crud made it's way to the back of the tank and plugged up the sock somewhat thus giving me a fuel starvation problem. Needless to say I got a new sock & fuel filter. That's about it.

 

Sorry but that is too funny. Glad you got it fixed!

 

Ok Kimmer, i just read 3 pages of this thread to find out Optis dont suck (at least not yours) and it was fuel problem. So at least u could finish with a statement of what your opti status is now and how long it been in use? Maybe edit your first post also and help save someone from reading the entire thread also?

Thx.

 

Agreed. I personally like my optispark now that ive ventd it.

(Though i can share with others misery on the optispark)

 

They still suck, the Chandler I put in last time lasted less than 5000 miles I just put in the Petris, it has less than 50 miles on it so we will see. P.S. I paid for the 5 year warranty.

 

Thank you!

 

You live in CA so we know is not the dense air.

After so many years working on aftermarket parts, DIY, and this forum I have learned (the hard way) the best electrical components are the factory products.

I got lucky with the MSD optis on Betty Boop, and The Ghost, but many in here claim to have issues with them.

The only small thing I can advice you is to disconnect the battery for few minutes, and try again. If that doesnt work buy a GM opti-spark ( buy the vented one). If this doesnt fix it, you have another issue, and that would be a new thread.

Good luck

 

I brought this thread back because I have a code 16, low resolution pulse on an opti with less than 100 miles on it. I may have a bit to add about the petris opti and his follow up service with the extended warranty. Hold on tight .

 

Damn, sorry about that kimmer. Will help with what I can

 

Something has to be eating your optisparks. Keep us informed, hopefully Chris makes it right.

 

Petri sent me an email saying to send it back and they will test it and replace it or $ back if its no good. This is the way it should be but in his earlier email he was rude and said he spent enough time with me already and I would just have to wait, all I asked him is if he had any ideas. So now I have to spend my time taking everything apart again.

 

Thats bull$h1t. There was another member here who had issues with one of the newer non-mitsubishi optical sensor petris units also.

I believe he stated that petris was rude to him also, threatening legal action, collections (after the guy disputed gettig a defective optispark via his credit card).

If there is an issue with the quality of these new non - mitsubishi optical sensor optisparks that they are using, then petris should be kissing everyones butt and not be rude about it.

He doeSnt reimburse you for your labor so i dont know what the attitude problem is.

 

The gm ones (ac delco new old stock, note: not ac delco remanufactured) are very hard to find anymore.

In 2001, i paid $600 (dealer markup) for just the base (cap/rotor not included) from a chevy dealer. It was an ac delco new old stock for my 93. I added a gen 2 cap and vented harness (using one of the 3 weep holes for the other vac line).

Sometimes if you search ebay you will find an old NOS one that some hobbyist took off an lt1/4 crate motor or someone had bought years ago as a spare.

Be prepared to ask a lot of question to the seller and expect to pay close to $500 for the real deal.

Can add a custom vent to it yourself

 

Seabright - i think i was following your posts earlier

Here is what i think happened in hour case:

I believe you had the dealer install an ac delco 'remanufactured' optispark. These are not the same as new old stock optispArks. In china, they do a great job replacing bearings and seals, unfortunately they do NOT replace the mitsubishi opticAl sensor which is they heart of the unit - however they do spraypaint the optical sensor black to make it look shiny and new (kind of like how they spraypaint fruits and vegetables in their markets to make them look more appetizing.....)

Heres my Experience:
The last time i looked for an optispark (in 2012), i was horrified to find that all the ac delco new old stock was gone. (For 92 thru 94 style.).

I ended up converting my cam/ timing gear to a gen 2 style.

I bought an ac delco remanufactured gen 2 optispark. It would start up and run for about 3 minutes then die. It would not restart until the car cooled completely, about 6 hours later.

When i took it apart was when i found that they had 'recycled' the mitsubishi optical sensor from a previous unit and painted it black.

Whatever test they perform on the sensor (if they do one) probably was done when the sensor was cold so the problem didnt show up.

-or-
Perhaps the coat of paint they put on the optical sensor contaminated something

I dont know what caused the original mitsubishi optical sensor to fail. Whether it was broke before the rebuild process or whether it got broke during the rebuild process (ie. The coat of paint)

I feel the frustration here. Its a PITA, have to go back in and change it all back out.

This is why i do my research and am willing to pay a little more to find an oem nos non rebuilt working optispark.

Also, if your car is a 92 thru 94, you need to rtv the 2 halves of the optispark (as a backup in case the seals crack) and add a vent harness or you may be doomed to the same failure.

This really is a case of 'they dont build them like they used to'

 

I have a 94LT1 that I'm putting cam, heads etc. this winter. I was going to put in a new opti, just as a precaution, as long as I had the old one removed anyway.
What is 24x? What is involved. Thanks

 

Please please dont be one of the many boneheads on here who 'proactively replaces' a working good OEM optispark with a non-mitsubishi sensor chinese replacement model - and then runs into trouble.

Take it apart, check it out (look for rust, moisture intrusion, bearing wobble, etc,) and if its still good I recommend just replacing cap / rotor and adding a gen 2 optispark vent harness (use late model cap which has one of the vent harness fittings and then use one of the 3 weepholes as the other fitting... obviously block off the other 2 weepholes and put a bead of RTV silicone around the optispark to keep moisture out - should the perimeter seal crack/ fail)

 

Thanks for the advice. Sounds sensible. I just want to make sure...a late model cap will fit on my 1994?

 

Yes. The cap from gen 2 will fit it. As i mentioned, it has one of the 2 nipples you need to connect up the gen 2 vented harness.

The other nipple is what you use one of the 3 weep holes for (drill one of them out to 1/8? I think and epoxy in a 1/8 straight vacuum connector to use that as the 2nd nipple. Obviously then you need to block off the remaining 2 weep holes).

The gen 2 opti base part has the 2nd nipple but you cant use that be ause the drive shaft is different)

Do buy the gen 2 vented harness becaus it includes a flow reducer and check valve on it.

The other ends of the hoses connect up to a manifold vacuum source (the hose that is connected to the weep hole) and the other one connects to a filtered air source - like in your intake ducting after the air filter

Btw, there was no saving my oem gen 1 optispark. At 26000 miles it was all rusty and corroded inside because the seals cracked and let moisture intrude in.

If you dont see that mitsubishi symbol on your optical sensor then its not an OEM part.

Good luck!

 

Thanks dizwiz24 for that great piece of info on converting over the Opti. When mine goes out I will be doing this. Thanks.
