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.
Repairs to date:
New spark plugs and wires, fuel systme service (injector cleaning, flush, change fuel filter), transmission flush with seals and gasket changed (was shifting poorly, not anymore), cleaned throttle body, oil change, air filter changed, new map sensor, electrical testing, new pcv valve
Mechanics suggested cleaning throttle plates, could this be the cause or is it something more sinister?
Any suggestions would be helpful....I am running out of patience and money!!
Mechanics couldn't find nothing and suggested a full tune up which included everything that I have mentioned (most I did myself). I can't afford their trial and error much longer
PlEASE SHARE YOUR WISDOM....IT IS GREATLY APPRECIATED
