I got my oil changed a few days ago and on this
past Saturday I cleaned my throttle body and after
I did that the car started running a high idle.
There's no leaks and i can't figure out what the
problem is.This issue is causing my car to fail
emissions. Please help.
What did you use to clean the throttle body? Is the check engine light on?
I used Throttle body cleaner and yes the light is on
I received two code. P0010 and P0171. I changed the camshaft actuator on the intake last year and it worked and I was able to get my emissions.
OOps most likely fouled up one of the servo motors in the body, try a parts store and get the code pulled and write it down then repost back here and we can go from there.
Welp... I put a brand new alternator in and my car just went out. The engine feels hotter then usual. The battery light came on but I was told that the alternator charges the battery. Please help
With it idling faster it will feel warmer than usual, so I must be missing something, you cleaned the throttle body to fix a high idle problem, or you now have a high idle cause you put on a new alternator?
I cleaned it because I received two codes P0010 and P0171. So after I cleaned it that's when the RRM meter went up to 3000(High idle).
The P0010 is the camshaft actuator circuit bank 1 and the P0171 is lean bank 1. So cleaning the throttle body would only cause the lean code to get stronger. Have you performed the throttle body relearn procedures? I believe it is number 4 in the shop manual for Malibu.
What's the relearn procedures?
Procedure 4 Throttle/Idle Learn Description The engine control module (ECM) learns the idle position of the throttle plate to ensure the cor- rect idle. Anytime the throttle body is cleaned or replaced, the ECM must learn the new throttle position. The idle may be unstable or a DTC may set if the throttle position is not learned. Conditions for Running the Throttle Learn Procedure • DTCs P0101, P0102, P0103, P0107, P0108, P0111, P0112, P0113, P0506, and P0507 are not set. • The engine speed is between 450-4,000 RPM. • The manifold absolute pressure (MAP) is greater than 5 kPa. • The mass air flow (MAF) is greater than 2 g/s. • The ignition 1 voltage is greater than 10 volts. Throttle Learn Important: Do NOT perform this procedure if DTCs are set. Refer to Diagnostic Trouble Code (DTC) List - Vehicle. 1. Start and idle the engine in PARK for 3 minutes. 2. With a scan tool, monitor desired and actual RPM. 3. The ECM will start to learn the new idle cells and Desired RPM should start to decrease. 4. Ignition OFF for 60 seconds. 5. Start and idle the engine in PARK for 3 minutes. 6. After the 3 minute run time the engine should be idling normal. Important: During the drive cycle the check engine light may come on with idle speed DTCs. If idle speed codes are set, clear codes so the ECM can continue to learn. If the engine idle speed has not been learned the vehicle will need to be driven at speeds above 70 km/h (44 mph) with several decelerations and extended idles. 7. After the drive cycle, the engine should be idling normally. If the engine idle speed has not been learned, turn OFF the ignition for 60 seconds and repeat step 6. 8. Once the engine speed has returned to normal, clear DTCs.
