Kuna, ID: what's different here
Kuna sits about 19 miles from Boise, roughly a 23-minute drive via the main highway. The area sees about 208 sunny days per year, with warm, dry summers and cold, clear winters. Cold winter mornings — Boise averaged a 33.1 °F minimum in February 2026 — can be when a weak coil finally fails. A mobile mechanic can come to Kuna instead of you driving to Boise.
What are the symptoms of a bad ignition coil?
A failing coil commonly causes a constant misfire in the affected cylinder and can trigger the Check Engine Light. Other signs include a rough idle, shaking, hard starts, and reduced power. Get the vehicle inspected promptly to restore performance.
How long does ignition coil replacement take in Kuna?
With easy access, a coil swap can take about 30–60 minutes. On hard-to-access engines, a professional job can take about 2–5 hours. Labor time generally runs 0.5 to 2 hours depending on vehicle design.
Why does the price range vary so much?
One coil usually runs $142–$234, but a full set or difficult access can push the bill to $500–$1,200+. Advanced ignition systems may cost about $200–$600 per coil. Labor is commonly billed at about $80–$107+ per hour.
