How it works - 3 simple steps

Step 1
Drop off & inspect

Mazda-compatible diagnostic scan reading Mazda-specific fault codes including i-ACTIVSENSE and i-ELOOP codes. Skyactiv-G intake valve carbon deposit assessment and throttle body inspection.

Step 2
You approve the estimate

Mazda 6-speed automatic service uses Mazda FZ ATF — not Dexron or generic ATF that causes shift hesitation. Skyactiv-G intake valve cleaning performed via chemical service or direct cleaning depending on deposit severity.

Step 3
Pick up your car

Post-service shift quality road test and idle quality check. All Mazda repairs backed by our 24-month/24,000-mile warranty.

Why Mountlake Terrace drivers choose Tom's B&M Auto

Mazda Skyactiv-G direct injection doesn't wash the intake valves with fuel the way port injection does — carbon deposits build up on the back of the valves and cause rough cold idle and slight power loss. Chemical intake cleaning treats deposits in the combustion chamber. Direct cleaning addresses valve back deposits more thoroughly.

Mazda FZ ATF is a specific fluid formulation for Mazda's 6-speed automatic. Using Dexron or a universal ATF causes shift hesitation and solenoid wear on Mazda automatics. We stock FZ ATF and use it in all Mazda automatic transmission services.

Intake valve deposit cleaning for DI Skyactiv-G engines at 60k-80k miles.

"I commute on I-5 every day and needed a shop I could trust with quick turnaround. Tom's has been that shop for three years running."
— Kevin P., Mountlake Terrace
★★★★★
"Check engine light diagnosis was spot-on — they found a failing MAF sensor, not the converter the other shop wanted to replace. Saved me $800."
— Angela W., Mountlake Terrace
★★★★★
"Fast, honest, and they explain everything. Showed me photos of the worn parts before the repair and after. That kind of transparency is rare."

From Tom's B&M Auto - serving Mountlake Terrace and the greater Seattle metro.
