My burb is dead in the water up in humboldt county. trans seal failed, and roasted my barely 2 year old trans rebuild. wifey has had it, and wont trust it, even with a new trans.
I am trying to help a buddy in a stock 88 GMc truck deal with the 108 blm issue as well. all sensors are new Ac Delco, and engine is mechanically sound. Seems to be a big problem with TBI.
Anyone know why this wouldnt start with the timing connector plugged in, but starts unplugged? Base timing confirmed, New distributor.
Also need to figure out a way to get this guys aldl cable out...
BRDW is the Export Tahoe BCC, Right?
I really wish i could get down there and help. 3.5 hours is a stretch.
Hey Mark...vortec heads... Maybe it would be advantageouse to start over using BNKM?
Ok, so he sent me a log, I told him to unplug the cts, reading drops to -40* and he apsaid it started running real good.
Why would it straighten up at -40, and run pig rich at 70*? Ideas?
Im lurkin here to Cali!
Tis the place to be!
One bit of info...My Burb was the same CCC setup. there isna white plug behind the glove box that plugs into the original harness. That plug has the key...
Cool, Thanks!
Condolences to you and your family:(
There are some things coming to light about my burb while I have been in the hospital...lotsa time for deep thought. For example, when I...
Hey Mark,
I have the small cap dizzy installed, and I got the proper latency settings from a stock ASDU...runs like dooky. Is there something Im missing? Will try to get a log asap, in the...
yeah, we are looking at everything. I have him adding a heated o2 for long tubes. then take the 10 k chip out.
crapola...should I have him pull A and/or B out of the ALDL?
No, he had the stock rochester and all sensors have been replaced 3 times trying to track down this issue. fuel pressure is currently at 12 psi.
Mark, all he has is an ALDL cable, and TPRT....is...
ok, i have a few logs from him. Everything goes pig rich on the blm and int on cl, but in open loop, after start, the blm and int look normal, but the vac is very low, and the iac is wide open like a...
Skip White is "Da Bomb!"
Got a really nice small cap EFI distributor from them.
Ok, Noted.
He has been convinced to purchase an ALDL cable...he was ready to buy a new harness.
For some reason, this conversation has me thinking back to a thread on another forum regarding 2 ignition modules for TBI, pertaining specifically to spark latency settings matching what is in the...
Yeah, I suggested the rocker re adjustment. This was happening before the rebuild too, I just found out. I will be Bald soon.
Nope, no DL. Most folks dont have the stuff, but I try to push ALDL cables at least, but have not suggested it in this case yet.
Mark, I was alarmed by the shaky vac too, but he says it settles to...
Yeah, i have banged my head on all the mechanical stuff pretty good.
He is in Ohio.
There seems to be so many TBI systems running really rich and causing problems...even when the engines are...
Hey guys,
I am trying to help another Truck owner figure out a problem.

Comp 12-388-4
Surging idle, constantly low BLM's....always 118 or below.
I am still having some issues every now and then, vac in drive, per the data dash, is 15"
But comp swears up and down its...
Hey Mark, dont forget about my supposedly small cam, and the problems it caused here. Seems to be an epidemic. 104 is way pig rich though, I have seen 108 on mine in drive.
TBI pressures are 9-13 psi, unless you are using a 454 throttle body from a 94-95 Truck. Too much PSI will cause problems.
Throttle bog issues have been mentioned with Carb intakes and TBI...
Vac...sorry.
