What symptoms you describe is definitely a T/B .But you did mention it was running find at first, the read out on your S/M I dont see anything that's alarming . I would start first with where I got gas last( maybe some water in it) , pull out a plug an see how it is firing, check plugs wire for connection,and how long has it been since the fuel filter has been replaced . Also is it running rich since it started idling rough,that could tell us a lot as well..

Scanmaster readings should be taken after warm up. Is the malfunction code (NAL) a typo?

Battery Voltage Low Check Alternator

Thank You for all replies, Voltage is good at regulator and battery but shows different at Scan Master ,about 2 volt difference, NAL could be typo, I think plugs are fouled gonna start from there. I got ahead of myself and to tell full story I left car show and it stumbled around,(was fine on the way) let me down ,got car on rollback & got it to the house, found the small wire(from Alternator) shorting out and was against case, It has been soldered and heat shrinked, got car running again, my guess it plugs are nasty from no fire I hope....I apologize for the confusion and appreciate all help.Are Scanmasters pretty good? One GN mechanic told me to buy Logmaster and plug laptop into it....Again Thanks Guys

Scanmaster is all that's required for now............and I think maybe the mechanic meant Powerlogger

Drive the car and get to operating temps then get home and let it come to idle for a few and then record readings and post them , Your TPS needs to read .44 to .46 at idle and with key ON engine OFF TPS needs to read 4.4 to 4.6 at WOT if you have a floor mat move it before you go to WOT, and at a warm idle your IAC needs to be around 10 or so .

Thanks for the help, Throttle body was reworked by Throttlebody.com bore went from 57mm to 62, I am glad this guy kept records, I have yet to pull panel & see about TurboTweak chip, gotta get over phobia of screwing something up, Thank You for help and replies, I had a 1969 Camaro SS, this is a whole nother animal, but when I got into I was definitely bit by the power these cars make,This car ran a 12:67 when it was right, nothing like some of you guys have ,fastest thing I have ever owned, Thanks for all replies again,try to get plugs and try again , Thanks

I heard that "back in the day" Florida required front license plates. First time seeing it.

THANKS FOR THE HELP, CAR IS RUNNING GOOD

TPS needs to be raised just a little .44 to .48 and 4.4 to 4.8 at WOT , IAC would help to be around 0 or as close as you can get it but otherwise she looks very good .
