Son's 96 LT1 Needs An Opti
He's been chasing running problems for a week or so now and has verified good working order on all of the most usual suspects - new plugs, wires, 02s, no vacuum leak, valve train, no codes, on and on and on. So with my help, we've touched all the bases.
Boils down to the Opti being the culprit. Before buying one I just ordered a scanner to see what the timing shows, but to get a head start on the purchase of a new ACDELCO Opti, am wondering who has the best price.
ACDELCO, only guys. Please no alternatives. Thanks for your consideration on that.

I used to use "thepartsladi" for all my WP and Opti needs. However, I can't seem to find them on fleabay now ?????? I think the last time I used them was 2 years ago for a '94 AC Delco Opti.
Anyone know if "thepartsladi" is still in business ?
They used to have the best prices on almost all OEM AC Delco stuff ...

Supposedly went belly up for one reason or another.
A search will find the details.

There are several other things I didn't mention too. Not my intention to list them all and ask for help but only to get the best price on an Opti IN CASE I need one, that's all this is about.
Once I scan and it tells me whatever it tells me I can go from there. My policy is to diagnose first then buy whatever parts are needed to fix the problem. I'm on top of this right now, but should I find I need advice, I know to ask here.

Diagnosis continues. He plans to spend the day in the garage on post as Ft. Lee checking various other things. Possibilty of a leaking injector(s) or FPR, MAF wiring, etc. I'm determined not to buy an Opti unless I really need to.
One of the last things I'll do is ship him my coil and ICM since they're known to be good. He can bolt them on and see if there's an improvement, if so BINGO! but if not we move on. I'm holding off on that since it'll call for my car being down for a few days.
I've developed mistrust in auto stores ICM testing since I've gotten very inconsistent results using three different stores. A few years back, one O'Reilly's said it was bad, another O'Reilly's, a couple of miles away, said it was good and AutoZone said BOTH!
Anyone checked the price on a new 96 ACDELCO Ignition Module lately? WOW! Be prepared for sticker shock.

My thinking is that if "Commanded" was NOT being translated into "Actual" the engine would let me know in short order since it wouldn't run very well with 15 degrees of timing advance at 2500 RPM, LOL
Just finished playing with it a little and it's doing what I hoped it would.

I'm sure you know this, but...
If you do a GM opti, take it apart and check it out before you install it. Everyone I've done has had horrible casting flash inside (it's plastic, so a file or dremel will knock it out in short order) and check the rotor screws. About 50% of the ones I've done have had at least one loose rotor screw from GM/Delphi.

Had no idea about the flashing and loose screws on ACDELCOs - although I'd read about loose screws on other threads.
THANKS MUCH for the heads-up on that.

Hi,
I picked up an OEM for ~$250 off eBay. Have seen them for as low as ~$150 clearanced. Start an eBay search engine and get email notifications.
Replace the following also while you have it off:
Water Pump,
Wires,
Thermostat,
EC sensor,
Spark Plugs.
My cap was badly carbon-tracked due to worn out spark plugs/excessive gap.
The greater the gap the more the timing is retired.
Best of Luck,
92WhiteVetteGUy
