Question about 1999 Chevrolet Silverado 1500
I have a 99 Chevy Silverado 4.3L 167000 miles, and after gunning it on the Highway I would get check engine light but it only happened every 6 months.
I run seafoam Injector/fuel system cleaner through and after about a week it goes out and runs smooth again.
Always try some type of fuel treatment/cleaner first, especially on high mileage vehicles before any expensive repairs.
