Hi .

No check engine light ON when the engine is running .

When we see this problem with no check engine light and no malfunction codes we go ahead and remove the throttle body and give it a good clean out with throttle body cleaner spray .

making sure the Idle control valve has been removed and also cleaned .

ones cleaned replace and test .before doing this job disconnect the battery .

Still same problem then you will need a good scan tool to check the live data stream for any high or low readings like the MAF,fuel trims etc

Please go ahead and clean the throttle body and Idle control valve .then get back to me if needed.

Need further assistance with this issue then please get back to me with the reply box below .
After rating there is no further cost for any other question relating this issue .
Kind regards Greg
