My 1966 small block has recently given me some difficulty, after the installation of a new Edelbrock carburetor and intake manifold. A sudden loss of engine power after 15 to 30 minutes of driving. Does not stall. I turn the engine off and let it cool down. Then restart and drive until...
Follow up
The dealer cleaned the connector, which needed it, and the ABS light went out and it works fine.For anyone else that needs a "Power Control Module" Here is the website(also on EBAY)PCMperformance.com.Hope all who are having this issue, it turns out as good for you as it did for me...
She's alive!!!!
Got car back today. Everything is working, just like old times. The new PCM did the job. What a relief. Stopped and started the car often, quick start everytime. Thanks for all your help. Got to admit this site is worth it's weight in gold or fiberglass whichever rocks...
You are not alone
I have the same issues and more for a while. I own a 97 Vette that I have had for 15 years. The 97 had modules and computer boards found only in that year. Since yours in newer you should be able to find what you need. Check out my discusion at : "Help, Abs and tcm lights...
Update
The dealer found several wires damaged and replaced them. Retested Camshaft sensor, still not getting the correct votage reading, so are replaceing that sensor, since engine is apart. They found the PCM in bad shape and replacing it. Part is in the mail, should be done next week...
Dealer evaluation so far.
Dealer pulled manifold and checked the Camshaft sensor. It was good. However, there is a voltage drop from the main harness to the sensor. They are now checking all wires looking for the bad one(s). That is the only thing they have found wrong so far. Waiting on...
Ignition
Car has 124000 miles on it. Owned car 15 years. Ignition switch and battery replaced last December. Car starts on very first crank when engine is cold. If driven and turned engine off, try immediate restart, it will not turn over makes sounds like low voltage crank. Car going back...

1. Started car. initial gauge check was completely normal, except "Check Engine Soon" light stayed on. Took car out on short drive. Speedometer working, ABS and TCS working, DIC working. All appeared normal. After 1/2 mile speedometer stopped working. Parked car, tried to...
Forgot to mention
Car came back from dealer on Friday. They cleaned and dried out EBCM. Said computer board was toast. Gave me the number on it #09356911 (no M), then came the weekend stuff listed.
Acts like a computer virus

Interesting
Please post here when you get any answer from them, good or bad.
I have also had the dealers reset th codes, but the malfunction happens again and again.. they also put in new modules twice.. still doesn't work after awhile.. I am at my wits end to find an answer.. any help will be...
Same thing
Mine did the same thing. Reset all codes and next morning it worked fine and still does. Chevy dealer says it is the EBCM module. No after market replacement for this item. Have a couple of specialty shops looking into the possibility of rebuilding this thing. I will post here any...
Dealer evaluation
Chevy dealer said the EBCM is bad needs replacing. GM no longer carries this part. On Ebay a used one is between $1000-$2000.00. My question for you, what did you do to disconnect yours and did the lights on dash go off or did you do something else?
More Info
All codes are current. The first time these lights came on and stayed on, there were all sorts of warnings and alarms going off. After I reset them and cleared all codes the lights come on after I start driving and stay on, but no more warning alarms. Car drives the same before...
First time for this problem. When starting car everything is normal, all lights go off then the ABS and TCM lights come back on. Traction Control switch on center console does not work when this started happening, but did before. No other brake light warning or steering warning comes on. Car...
