For the last month my 93 Lumina 3.1 has been nothing but a headache. Everytime I think I have it figured out something else goes.
First off my code reader is reading 12, any one got a better explanation than systme good, cause obviously it is not!
Symptoms: Drives good for a while and then stalls at a light, when I am coasting it still feels as though I am pressing the gas.
well, code 12 means no codes have been set, not much more you can say about that. I am just wondering since you say it seems like "coasting it still feels as though I am pressing the gas." If it isnt your transmission TCC switch possibly not unlocking? would also explain stalling when stopping, depends on what it does when it stalls, if it cuts off clean, bucks, jumps and then stalls, or if it feels like it still trys to pull and you are using the brakes to stop it, sorta like trying to stop a manual transmission car without depressing the clutch?
High rpms with throttle less than that rpm, could also be a vac. leak in a hose around the engine too. Ever check the PCV valve and hose under the intake top plenum? Just putting idea's to ya.
