Repair costs for a misfire on cylinder 5 vary widely, driven by the root cause, parts quality, and labor time. Typical factors include whether the issue is a faulty spark plug, ignition coil, fuel injector, or a compression problem, plus regional labor rates and shop fees. Cost transparency helps owners budget accurately and compare quotes.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Diagnosis | $80 | $120 | $180 | Includes scan and misfire code pull |
| Spark Plug Replacement | $20 | $60 | $120 | Per plug; assumes access is easy |
| Ignition Coil Replacement | $60 | $180 | $350 | One coil; higher for premium coil |
| Fuel Injector Service/Replacement | $150 | $350 | $700 | Seat cleaning vs replacement |
| Compression/Head Gasket Issue | $400 | $1,200 | $2,500 | Major repair if cylinder is damaged |
| Labor (total) | $120 | $400 | $950 | Hours × hourly rate; varies by shop |
| Misc. Fees/Taxes | $20 | $60 | $120 | Shop supplies, disposal fees |
Overview Of Costs
The typical repair price for cylinder 5 misfire ranges from about $300 to $1,800, but more complex root causes can push totals higher. When the misfire stems from a simple spark plug or ignition coil issue, owners often see the lower end of the spectrum; if the cylinder has suffered mechanical damage or a faulty injector in tandem, costs rise quickly. Estimates assume a mid-range part quality and standard labor rates in urban U.S. shops. For clarity, both total project ranges and per-unit ranges are provided below.
Cost Breakdown
Assumptions: one cylinder affected, vehicle within manufacturer specifications, standard 3–6 year old model, no pre-existing damage. The table below shows cost components, with totals and per-unit references where applicable.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Diagnosis | $80 | $120 | $180 | OBD scan, misfire identification |
| Parts | $20 | $230 | $900 | Depends on spark, coil, injector, and potential mechanical parts |
| Labor | $120 | $400 | $950 | Hourly rates vary by region |
| Permits/Taxes | $0 | $40 | $100 | Dependant on location |
| Delivery/Disposal | $0 | $20 | $50 | Old parts and fluids |
| Warranty | $0 | $50 | $100 | Labor or parts warranty |
| Overhead/Profit | $30 | $90 | $180 | Shop margins |
| Taxes | $0 | $25 | $60 | State/local |
What Drives Price
Key price drivers include the root cause and the cylinder head’s accessibility, plus whether the repair involves single parts or a combination. Spark plug and ignition coil failures are common and often inexpensive, whereas injector cleaning or replacement can raise costs by hundreds. If a compression test reveals a leaking valve or blown head gasket, the price escalates, sometimes dramatically. Regional labor rates and vehicle make/model also color the final bill.
Labor, Hours & Rates
Labor costs scale with time and regional wages. Typical shop rates range from about $85 to $150 per hour in many U.S. markets. A straightforward spark plug or coil replacement might take 0.5–1.5 hours, whereas diagnosing a multi-component issue or performing a full cylinder repair can require 2–6 hours. For context, a 1-hour diagnostic plus a 1–hour replacement could land in the $200–$400 range in many areas, while more elaborate fixes approach or exceed $1,000 in high-cost regions.
Regional Price Differences
Prices vary by region and urban versus rural markets. In the Northeast metro areas, expect higher rates than the national average; the Southeast often shows mid-range pricing; rural areas tend to have lower labor charges but may incur higher parts/shipping costs. A typical misfire fix that involves common parts (plug + coil) may be 5–15% cheaper in rural zones, while injector work or gasket-related repairs can exceed regional deltas by 20–40% in dense markets.
Real-World Pricing Examples
Three scenario cards illustrate common outcomes with specs, labor times, per-unit pricing, and totals. Assumptions: region, vehicle type, and labor hours vary by scenario.
Assumptions: region, specs, labor hours.
Scenario: Basic Cylinder 5 Misfire (Spark Plug or Coil)
Specs: 1 misfiring cylinder, basic coil and plug swap, no additional diagnostics beyond standard scan. Labor: 1.0 hour. Parts: standard spark plug + ignition coil pair if needed. Total: $180-$420; Parts: $60-$180; Labor: $120-$240.
Scenario: Mid-Range Fix (Injector/Advanced Diagnostics)
Specs: misfire with suspected injector, possible cleaning or replacement, diagnostic time plus component swap. Labor: 2.0–3.0 hours. Parts: injector or cleaning kit. Total: $420-$1,150; Parts: $200-$600; Labor: $220-$600.
Scenario: Premium Repair (Compression or Head Work)
Specs: cylinder requires compression test, possible valve/seat work or head gasket, multiple components. Labor: 4.0–6.0 hours. Parts: high-end injector, seals, gaskets. Total: $1,000-$2,800; Parts: $500-$1,400; Labor: $500-$1,800.
Additional & Hidden Costs
Hidden or added charges can alter final pricing. Vehicle access issues, dashboard code resets, or needing a rental car while repairs are performed can add costs. Some shops charge a diagnostic fee even if you proceed with the repair, while others roll that into the final bill. If a service includes reprogramming or software updates, expect small, one-time fees. Ensure quotes itemize parts, labor, and any disposal or environmental fees to avoid surprises.
Cost By Region
Comparative regional costs help buyers anticipate differences. In urban West Coast markets, total repair for a single misfire can top $1,500 when including head gasket concerns. Midwest suburban shops may charge $350–$900 for a coil/plug fix, while rural Southern shops could land in the $250–$650 range for similar parts. Always request a written estimate with the hourly rate and expected hours to gauge regional variance accurately.
