It happens at idle, highway speed and everywhere in between. Quiet for 10 seconds after start, then it begins. It sounds like it is searching; overshoots, undershoots. Interferes with acceleration. 114K miles. 2006 Hammer Time Ultimate Carjunky / Moderator Nov 28, 2019, 8:24 AM Post #2 of 4 (1510 views) Re: 2.3L Mazda 6 mild rpm pulsation Sign In Start out checking for any stored trouble codes. If there are any codes, post the numbers here before going any further. If no codes found, then check carefully for any vacuum leaks and then clean the throttle body with some throttle body cleaner to include both sides of the throttle plate and surrounding bore. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Vacuum leaks - I'll have to check that. Hammer Time Ultimate Carjunky / Moderator Nov 28, 2019, 9:00 AM Post #4 of 4 (1501 views) Re: 2.3L Mazda 6 mild rpm pulsation Sign In Also check for any air leaks in the intake snorkel between the MAF and the throttle body. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
