Going to move towards RWD chassis soon, so it's more fun to use. Z7 kit needs gone, MP112/L26 chillin', 2 GenV's on ice, and T67 currently on my L32. Cheaper than LSx playtime yo tinker with this.

I'll gladly do mega builds with my stash! Getting stationed at a new spot next year, and might need projects.

@  kevandkaye : (05 August 2021 - 10:52 PM)

How cool would it be for everyone here who has leftover parts, send them ALL to one person for a superbuild? Sorry, peeked in and got chatty!

@  kevandkaye : (05 August 2021 - 10:50 PM)

Sure am missing the days when Buicks were built by Buick.

@  kevandkaye : (05 August 2021 - 10:50 PM)

Paul's a mod?!?! I take you more for a resto......

@  ejguillot : (03 August 2021 - 10:28 PM)

Well, my project Buick is dead. Piston smacked a valve, piston/block/head is trashed. That killed my enthusiasm. Will be posting a parts for sale list real soon.

Its even worse... he has been a memeber for 13 years and has 2 active posts.....

@  dezldave961 : (21 July 2021 - 11:38 PM)

Some people don't know how the internet works, and think deleting after posting somehow works like an Etch-A-Sketch. (You made 2 posts 13yrs ago about fixing an ignition switch, which I'd never know if you didn't ask about deleting... Look up Streisand Effect.)

@  Marchi1 : (21 July 2021 - 01:53 AM)

and just quit using it. there is very little update and while I can delete it why would you?

@  Marchi1 : (21 July 2021 - 01:52 AM)

that hurst I have been here in less than months

@  esqueue : (15 July 2021 - 05:50 PM)

A moderator hasn't been here for months

@  esqueue : (15 July 2021 - 05:48 PM)

How do I get my account deleted?

SELLING 99GS SEE FORUM, THANK YOU

@  dezldave961 : (16 June 2021 - 11:10 PM)

Good deal. I'll be resolving some issues when I get back from a work trip, as well.

@  ejguillot : (14 June 2021 - 01:05 PM)

Also rechecked the flexplate and rocker arm bolts, all were torqued to spec.

@  ejguillot : (14 June 2021 - 01:05 PM)

Update on the tap/knock noise: resolved most of it by resealing my exhaust. Front header to crossover pipe leak - noise at 1/2 engine RPM.

@  ejguillot : (04 June 2021 - 07:15 PM)

I'll recheck those, thanks for the heads up.

@  dezldave961 : (03 June 2021 - 04:50 PM)

Also, check that the rockers are all torqued, still. Re-usable bolts like to be around 25 or so, but settling in from running may back one out that was torqued while partially under load on a cam lobe.

@  dezldave961 : (03 June 2021 - 04:48 PM)

Did you do anything with the flexplate? Those 3 bolts tend to come loose and rattle over time, if not torqued with loctite.

@  ejguillot : (03 June 2021 - 04:46 PM)

doing OK. Tune's all fixed, but hearing a tap/knock noise from my engine that is no longer fading with higher RPM. Not good.

Has anyone seen a C1323 code?

DTC C1323 PCM to EBTCM Delivered Torque Circuit Malfunction - that's what I sometimes get.  Seen only when I go WOT in 1st gear.  Apparently the engine is not reducing torque output enough to keep the traction control happy.

 

Wondering if anyone had ever seen it.  I do have injector shutting off disabled in my tune (as suggested by Jerry's Tuning Guide).

 

From the FSM:

 

Circuit Description
The traction control system uses the antilock brake system in conjunction with the PCM fuel and ignition controls to limit drive wheel slippage during acceleration. The PCM controlled portion of the traction control system reduces engine torque by performing one or both of the following actions:
 
    •  Retarding the spark timing and alternating the air/fuel ratio 
 
    •  Shutting off up to three injectors 
 
The EBCM/EBTCM sends a torque request to the PCM via a Pulse Width Modulated (PWM) signal requesting the desired torque level for proper traction control system operation (CKT 463). The PCM then provides a delivered torque PWM signal (CKT 464) informing the EBCM/EBTCM how much actual torque the engine produces.
 
Conditions for Setting the DTC
DTC C1323 will set when one of the following conditions occurs:
 
    •  A malfunction exists in the delivered torque circuit (CKT 464). 
 
    •  The signal is out of range. 
 
Action Taken When the DTC Sets
    •  A malfunction DTC stores. 
 
    •  The ETS/TCS disables. 
 
    •  The amber ETS/TCS indicator turns on. 
 
Conditions for Clearing the DTC
    •  The condition responsible for setting the DTC no longer exists and the Scan Tool Clear DTCs function is used. 
 
    •  100 drive cycles pass with no DTC(s) detected.

Never seen it - closest thing was my car misfiring/shutting off when I would go WOT and it turned out to be the fuse box itself was bad.

 

Can only be so many things though. I have an older copy of SI if you need to use it for a schematic or something
