UF837 / 94051 Service Scenarios for Chevrolet Spark 1.4L L4

Rough Idle or Cylinder Misfire

Inspect the affected coil, spark plug, boot, connector, wiring, and plug well. A misfire code identifies a condition to diagnose and does not by itself prove every ignition coil or spark plug is faulty.

Hesitation Under Load

A marginal ignition component may become more noticeable as ignition demand increases during acceleration. Check the affected cylinder and spark plug condition before replacement.

Four-Cylinder Ignition Maintenance

The 4+4 package supports a matched-count ignition service when the exact 1.4L L4 application and original components match.

How to Confirm UF837 and 94051 Fitment Before Ordering

Confirm 2016-2021 Chevrolet Spark and exact 1.4L L4 engine.
Compare UF837 and KD-7209 with the original ignition coil.
Check connector shape and keying, coil body, mounting point, and boot profile.
Confirm the original spark plug or service information matches 94051.

Installation Checks for the UF837 & 94051 Chevrolet Spark Kit

Work on a cool engine.
Inspect wiring, connectors, boots, plug wells, oil, and moisture.
Compare all new parts with the removed components before installation.
Use vehicle service specifications for spark plug gap and tightening torque.
Recheck stored or returning misfire codes after service.

Important: These are BDFHYK OE-style aftermarket service components, not factory-branded Chevrolet parts. Continue diagnosis if symptoms remain.
