I have recently replaced the MAF Sensor aswell as the Camshaft Position Sensor. When i drive the car it doesnt appear sluggish or to have any problems. When the car is idling the engine RPMs will fluctuate up and down by a hundred or so. Also after the test drive, there was some smoke coming from under the drive side of the engine, not sure if this is related but either way it is not good.

I do own a scanner and it has not produced me with any codes nor a CEL.

Thanks in advance!

Hi Partial, Welcome to 2carpros and TY for the donation.

Clean out the idle air control valve and the PCV and EGR valves-also look for vacuum leaks. For the smoke could be an oil leak from the valve covers, oil pressure switch-Fnt/Rear seals-look closely
