Cylinder 6 Misfire Repair Cost Price Guide for U.S. Buyers 2026

Repairing a cylinder 6 misfire is a common, price sensitive job. Typical costs depend on the root cause, parts quality, and labor time. This guide provides realistic cost ranges in dollars and the main drivers behind price movements. It uses the exact phrase cost or price within the opening section and headings for quick search relevance.

Overview Of Costs

Understanding the big picture helps set a budget quickly. The total project usually spans two main parts: diagnostic time and repair parts plus labor. In most cases, diagnostic time is bundled into labor once a misfire is confirmed. Costs vary by vehicle make, engine design, and the failure mode on cylinder 6. For many U S shoppers, a typical misfire repair falls within a mid range, but scenarios can push the price higher when multiple components are involved.

Assumptions: region, fuel quality, engine design, fault isolation time.

Summary Table

Item Low Average High Notes
Diagnostic Fee $50 $100 $180 Some shops waive if repair proceeds
Parts (cylinder 6 related) $15 $180 $1,000 Depends on coil, plug, injector, head gasket
Labor $60 $250 $750 Hours required depend on fault
Total Project $125 $450 $1,900 Typical to high depending on fix

Cost Breakdown

Materials Labor Equipment Permits Delivery/Disposal Warranty Taxes
Ignition coil or coil pack $60-$320 O2 sensor test, scan tool 0 Included in service if needed 12 months Varies by state
Spark plugs Included in labor if replaced 0 0 0 24 months 3–9%
Fuel injector or injector cleaning $80-$420 Removal time 0 0 6–12 months Varies
Head gasket or compression concerns $400-$1,000 Extensive labor 0 0 12 months Taxed

Pricing Variables

Engine design and cylinder layout drive cost. Direct coil or spark plug replacement on cylinder 6 is straightforward and cheaper than chasing a faulty injector, and far cheaper than a head gasket repair. Vehicle age, availability of replacement parts, and the shop’s hourly rate are major price levers. Special tools, such as a high end diagnostic scanner, can add small overhead but may reduce overall diagnostic hours when faults are subtle.

Regional Price Differences

Prices shift by region due to labor markets and parts availability. In three broad U S areas, expectations differ by roughly plus or minus 15 to 25 percent from the national average.

Urban Centers

Higher labor rates and more limited technician availability can push totals toward the upper end of the spectrum, especially for newer vehicles or specialty coil designs. Expect faster service but higher price.

Suburban Markets

Typically balanced between cost and speed. Parts availability is solid, and shops often offer transparent pricing with modest premium for diagnostic time. Budget predictability is common here.

Rural Areas

Lower labor rates help reduce totals, but accessibility and parts delays can extend turnaround. Outlier costs arise when parts must be special-ordered.

Labor And Installation Time

Labor costs hinge on how long the fault takes to confirm and repair. A straightforward misfire on cylinder 6 may need coil replacement or spark plug swap, while complex issues like a leaky injector or compression problem extend hours. Typical job times range from 1 to 4 hours, with hourly rates commonly between $80 and $150 in many markets. Labor hours are the critical driver of total cost.

Additional And Hidden Costs

Some repairs expose ancillary expenses. For example, replacing a coil pack may require fresh boot seals, or a failed injector might necessitate a wiring harness check. Vehicle access, engine heat shields, and refrigerant service aren’t typical but can appear. Hidden costs often surface after parts removal.

What Drives Price

Two niche drivers significantly influence Cylinder 6 misfire repair pricing. First, ignition system design: coil-on-plug systems with multiple coils or specialty coils cost more. Second, potential head or valve concerns: if compression testing reveals cylinder 6 anomalies, the repair scope grows. These factors set the price ceiling in many cases.

Real-World Pricing Examples

Three scenario snapshots illustrate typical quotes and what they include. Each card lists specs, labor hours, per-unit prices, and totals to give a sense of scale.

Scenario 1 Basic

Specs: coil replacement on cylinder 6, standard spark plug, no additional work. Labor 1.0–1.5 hours. Coil pack $120, spark plug $8 each, diagnostic included. Total around $180-$300 depending on shop rate. Per-unit note: $/hour approximately $120. Assumptions: modern inline-four, average coil price, no extra parts.

Scenario 2 Mid-Range

Specs: coil pack plus fuel injector service. Labor 2.0–3.0 hours. Coil pack $180, injector cleaning or minor replacement $150, spark plugs included. Total around $350-$700. Per-unit note: $/hour about $130. Assumptions: V6 or V8 engine with one injector affected, standard tools available.

Scenario 3 Premium

Specs: suspected head gasket or compression issue on cylinder 6 with full diagnostic overhaul. Labor 4.0–6.0 hours. Parts include high-end coil pack $250, injector replacement $350, possible head gasket $900. Total around $1,100-$2,500. Per-unit note: $/hour about $140. Assumptions: older vehicle, limited aftermarket parts, extensive disassembly required.

Budget Tips

Plan ahead with a clear diagnostic scope to avoid surprise charges. Ask for a written estimate covering diagnostic time, part prices, labor hours, and potential add-ons. If feasible, obtain quotes from two shops to compare parts availability and labor rates. Consider moisture and fuel quality based maintenance to prevent recurring misfires. Some providers offer a bundled diagnostic and fix price for common cylinder 6 misfires, which can stabilize budgeting.
