well i need to know if anyone has any ideas on where to start .up until about 6 months ago the car was fine now it seems that the car has a mind of its own .when i start the car up the idle will be fine sometimes but after about 5 to 10 minutes the idle will start jumping up and down and it will stumble real hard but it wont die. just keeps going up and down .so when i take it out for a drive it can be a pain .like when i come up to a light and stop i put it in park or neutril (sp) cause if not it stumbles like you wouldnt believe it and when i take off and give it gas lightly it stumbles real bad now if i was to put my foot into it theres no problems with taking off this problem seems to get worse when the car gets warmer .now the fun part its time to smog the car so i take it in for a pretest and they do what they got to do and they tell me it wouldnt pass due to the stumbling they also said it was misfiring above 50 mph and wanted 186$ to do a diagnostic to find out whats wrong which i cant afford right now .so i take the car to a friend shop and he hooks it up to a machine and says for some reason its not allowing him to pull any codes and he suggest maybe getting a new brain and then go from there so does anyone got any ideas what this may sound like thanks james
