On my '81 DeVille when I go to run the diagnostics test it shows 30 as the only code, 88 and 70 meaning the beging and end of it. When I start the car it starts and then after a few seconds trys to die until I put my foot on the gas a little. Is this the ISC or TPS? How can I test each to see what it is?
After I get it to stop wanting to die, only does it for about 30 seconds when cold, it idles and runs just fine. Any thoughts? Thanks
