Hey Walt, it's good to hear you've got it together and running now, hang in there & you'll get sorted out! I agree w/Mick, I had a bad O2 and my car wouldn't run worth a damn no matter what I did. Are you logging? If so the cross counts will tell the story.....no matter what you do it won't smooth out with a bad O2. Congrats brotha stay the course, your getting close 
I do not have a data logger yet. I am going to have to get one this week.
I feel bad because Mseven has been trying to help me out and I dont have the tools to answer his questions.
What is the best system for datalogging for the price? I was looking at the datamaster but I am unsure. Even if the system can read and write that may be better. Perhaps a Moates system. I will order what you guys recommend this week. Thanks again everyone for the replies, Walt

Ok this is going to sounds stupid and basic but make sure th chip is seated fully in the ECM. Since it sits upsidedown when the ECM is bolted in place, mine lossened up on me and started acting just as you described. Mine was spitting raw fuel out the tail pipes and wanted to stall.

Hey guys,
I removed the ecm and looked at the chip. I moved it around and it felt loose. So i pushed it in and it clicked. I did throw a code last time i fired it for an invalid mem-cal. Kubs good call.
Next up I went to go replace the o2 sensor and it was only finger tight. Thats my fault, and i wont try and make a excuse for it.
I tested the CTS input at plug c16 of the ecm and it read 2.5 volts. I think that is good.
I just changed out the oil again because it had the sent of fuel due to running rich.
My buddy should be here in 20 min or so and I am going to fire it up.
I will let you guys know how it goes. Thanks again..

I fired it up and the it is not running nearly as rich as it was.
The only code I am getting is Code 41, faulty MEM-CAL.
The chip is definitely secure.
I am going to call PCMFORLESS to find out what would cause this.
Has anyone gotten this code before?
Thanks, Walt

The moates systems (APU1, OSTRICH) are great products if you are tuning yourself or uploading a tune being emailed to you.

Problem solved..
When I connected the stock MEMCAL to the pcmforless memcal I placed it one row of pins off.
I have not had a chance to start it yet. I think we can all agree on two things, that was probably the problem and if you ever meet me do not let me install a chip in your car.
Does anyone know if this would have done any damage to my ECM?
I will be buying a Moates setup with the Data Master. I would like to learn what is going on with my car in the future.
After I start it I will let you guys know how it ran. I will also get a little video clip of it and post it.
Also I would like to thank everyone who took the time to reply and try and help me sort out this issue. Thanks again, Walt.

Glad you got it figured out. Don't feel bad, it's all new stuff til you've done it once. Even after umpteen changes in my BIN (trying to get perfect driveability), I've plugged it in backwards once or twice.
You'll be glad to get the logging software. There's great peace of mind having that feedback. Plus, it makes diagnosis of future problems much easier.

To save you a little time here is what you need to order to start dataloging with Datamaster..WW
Here is the Datamaster programs, the one you need for your 90 vette is #DM35X8D. You get 20 free datalogs to try it out and then have to buy the program...

You also need this cable to hook up the laptop to the car...

Glad you figured it out! I always check the simple things before I take major parts off and/or spend money. Now go out and enjoy it!
WW thanks for the links. Im looking to start datalogging myself.
