Engine Repair at our Escondido shop
Escondido Auto Repair lists “Engine repair”. The line names above are exactly what each shop posts on its own service board.
Escondido Auto Repair is a full-service repair shop, not a smog station. If this work follows a failed smog inspection, the retest is done by Smog Check Escondido at the same address; bring the inspection report so the shop is not paying to rediscover what failed.
Ask for a written estimate at the counter before work begins. If a repair follows a smog failure, California's Consumer Assistance Program may cover part of the cost — apply through BAR before the work is done. Your rights as a repair customer, and how to raise a dispute, are in our consumer-rights guide.

Engine Repair questions
What causes a rough idle or engine misfire?
Fouled spark plugs, a failing ignition coil, vacuum leak, dirty fuel injector, or low compression are the most common causes of rough idle and misfires.
- P0300 (random misfire) or P030x (cylinder-specific) codes point directly to the cylinder
- Ignition coil failure is common and often causes intermittent misfires
- Vacuum leaks create a lean condition that mimics misfire symptoms
- Dirty injectors reduce fuel atomization and cause incomplete combustion
- Prolonged misfires overheat and destroy the catalytic converter
Per ASE A8 engine performance and ASE L1 advanced diagnostics.
What is included in a tune-up?
A modern tune-up replaces spark plugs, air filter, and fuel filter, inspects ignition wires and coils, and includes a diagnostic scan — not the carburetor-era procedure of decades past.
- Iridium/platinum plugs last 60,000-100,000 miles; copper plugs 30,000
- Misfires from old plugs cause poor fuel economy and can damage the catalytic converter
- Fuel system service (injector cleaning) is often added for high-mileage vehicles
- Full diagnostic scan identifies any other pending codes at the same visit
- Well-tuned engine supports cleaner emissions and helps smog pass
Per ASE A8 engine performance standards and manufacturer service schedules.
