Needed. Good GM garage to diagnose the Camaro.

Laugh at carbs all you want! My Coronet doesn't seem to miss many meets or need to be disassembled at the lot!

Yeah, that low-tech, 70's carb crap really sucks, don't it? And people want to kick me in the nuts when I say how much I like carbed engines.

Carb engines are cool. I especially like carbs on motorcycles.

I have thought about getting a Carb on mine.

I would love to be able to tune my car with a screwdriver.

Carbs ftw

Carb > old style fuel inj
New style fuel inj > carb

So what is the plan Kevin? Did the piece get shipped out today? Are you planning on ripping the old one out? Unfortunately this thing stuck in my head today and I logically thought about this a bit.

Ok here is what we know

Inconsistent firing causing drivability issues: fact

bad coil :fact

Optispark distributor a shitty set up :fact

Now, I have a few questions?

How many Distributors has this car eaten in the past year? I believe its is 2 or 3, maybe 4 now even if they are shitty that just is against the law of averages.

Now I'm not constantly seeing LT1 F bodies all over the place dieing and not running right.

My gut is telling me that the opti is more symptom then the real problem.

Putting a carb on a LT1 give you the option to run a nice distributor but the intake is not good if your looking ot make big power. If you want to do that you need to mod a SBC intake to work. I agree with JD

carb>old efi
new efi >carb

Carb > lt1 fuel injection

My car did the exact same thing on optis 2 and 3. It was a more than frustrating situation. I checked every ignition component over and over only to lead it back to....that damn opti. Finaly got an AC delco and havent looked back.

Blackout, if you get a new part do you plan on doing this yourself?

Opti and be done ... we checked everything else ...


The only thing that should be replaced next is rear tires ...

This was no shot at your work JD on the car, sorry if it came across that way, but man the rate of failure on those Opti's is almost unbelievable!

Not at all. I never even thought about it . And ya it is hard to believe the failure rate . It's like plastic surgery

I told you so

Finally!!

hahahaha yes!

Nobodies fault but GM, that opti-spark is a huge piece of shit.

You make my points much better than I do

Isn't the opti spark actually the one piece on those cars that was a Mitsubishi design, EVO's are the greatest thing since Duster's made sliced bread so that can't be your problem

^ No sir, Mitsubishi only designed the optical sensor part of opti spark. The cap and rotor are typicly the parts that malfunction. They go bad mostly due to GM placing the opti in an area that is exposed to heat and moisture.

I think the optical sensor is what the problem is in this case

Well looks like Mitsubishi got you fuckers good then

Hahaha Stupid jap crap

dude your sig geeks me the fuck out aHAHAH I LOLed twice now

Okay, update.

The new Distributor arrived in SP today according to the tracking, so I should be able to hit this on Sunday. Yes, I'll be doing it myself. Since I already have a vent line setup, I'm going to seal the cap to the body to make sure it won't suck up water.

JD has been a HUGE help with this. If we hadn't done an opti replacement already, its a good chance I'd take forever to do this since i would have NO CLUE how to.

Its a good chance that either the bad coil or the bad harness took this accel opti out, but its also a good chance that the accel opti was a DOA POS right out of the box. I've gone over all the wiring, and after replacing the opti harness it all checked out. I have to hit the parts store today for another set of WP gaskets, silicone, some gasket adhesive and a coolant drain pan but otherwise i should be good to go. i picked up some extensions and some swivels at Sears last night too.

The biggest problem with the aftermarket style opti's is the LACK of the mitsu sensor. Apparently they are pretty good.... but the AM companies use inferior parts. Just to make things a bit easier, I'm pulling the radiator/shroud assembly straight out of the car..... that should give me enough room to do everything from the top, and not have to fuck around under the car at all. Keep your fingers crossed!

good luck!

If it doesn't have the Mitsubishi sensor don't put it on your car.


THE ONLY OPTI SPARK TO GET IS AN AC DELCO
