1998 Chevrolet S10 Q&A

1998 Chevrolet S10 Question: my service engine light came on and it blinks while I drive what does that mean

this happened two days ago I turned my truck on and it started sounding really shaky and even to idle it takes time. I changed out spark plugs but still have that problem. I also did oil change -
Answer 1
that's a check engine light. you need to have it scanned for codes to see what's wrong. some parts stores do it free; some shops will waive diagnotic charges if they do the repairs. -
