Check what maintenance is actually due
Send year, make, model, engine, mileage, and records for spark plugs and filters. Plug type, service interval, and access differ by engine. The manufacturer schedule and prior invoices help avoid replacing parts that are not due.
A misfire, rough idle, or warning light may need diagnosis rather than routine service. Ignition, fuel, airflow, compression, and control problems can create similar symptoms. Tell us when the fault occurs so the visit is scoped accurately.
Verify the offer and apartment access
The existing $349 starting offer applies only to eligible standard-access four-cylinder vehicles with standard engine and cabin filters. It is not a flat amount for every car. Hye Tech verifies the engine, parts, and access before dispatch.
A shared garage or driveway may restrict hood access and engine-running checks. Confirm that property work is permitted and provide the parking details. The engine must cool before spark plug service; a closed garage is not suitable for running tests.
Keep active engine faults separate
Share maintenance receipts and note if a symptom appears cold, warm, or under load. Do not assume a tune-up will fix a check-engine warning. Codes and misfires should be evaluated based on evidence before additional parts are installed.
The approved maintenance scope is confirmed before work. Separate diagnosis or repair requires its own estimate and approval. If the vehicle is outside offer eligibility, Hye Tech explains the applicable scope and price before scheduling.
