ae software needed barrow??
Is anoone close to me in NC? I am about 40 miles west of greensboro. I need to run a buzz and cct test when the motor is cold. I spoke with nc hornet on here but his is already loaned out.
I have either a trans issue or a bad injector when the motor is cold.
The pcm will allow the tc to lock at approx(175 degrees) I think. AT this time i get a shudder, pretty serious one. If i lock the tc before the computer does(even colder EOT)(toggle switch) it also shakes.(replaced the tc, no fix)
Once the motor gets fully wartmed up, no more issues, all is fine and smooth.
I dont know if i have a weak injector when its cold. Or something in the trans needs to get fully warmed up to work correctly. But its very consistent. It will shake in the morning, when i lock the tc, or the pcm locks on its own after its sat all nite.(i think the pcm allows it to lock around 170 degrees)
It starts right up. Does not sound like it has an injector miss. Once the motor is around 200 or the 195 what ever it is all is smooth.
