I do not speak spanish, please write back in english, All i understand is that you have a 2001 Buick Lesabre with a 6 cylinder engine 3.8, And that you had a service done, with sparkplugs and wires and injector cleaning and you still have same problem,
you wrote that the problem is that i turn off when i walk and high??? what does that mean? what is the problem.
The light is on to indicate you have been locked out and the engine disabled. You must now have the dealer scan the system and determine the cause of the malfunction in the security system, it is likely the ignition lock cylinder key code reader that is defective.
When a misfire occurs, engine speed will fluctuate. If the engine speed
fluctuates enough to cause the Crankshaft Position (CKP) sensor signal
to vary, The Powertrain Control Module (PCM) or Electronic Control
Module (ECM) can determine that a misfire is occurring.
When is the code detected?
- Engine Cylinder #5 and #6 is Misfiring.
Symptoms: - Engine Light ON (or Service Engine Soon Warning Light) - Lack/loss of power - Hard start - Engine hesitation
Possible Causes: - Improper spark plug at cylinder #5 and #6 - Insufficient compression at cylinder #5 and #6 - Incorrect fuel pressure - The injector circuit is open or shorted at cylinder #5 and #6 - Fuel injector #5 and #6 may be faulty - Intake air leak at cyli
Possible Solution: - Perform Injector Service - Replaced Spark Plug #5 and #6 - Replaced Injector #5 and #6 - Replaced Ignition Coil #5 and #6
Do you have check engine light on???if so scan it OBD 2 yue$$ding isn't the way to go,if you don't have a check engine light on then perhaps coil pack!!! coils do run intermittent some times! and not trip the eng light on !!!!this would be a great place to start.Hope this helps
