2004 Chevy S10 ZR5
Anyone else’s s10 have a slight shake at idle and not a smooth idle, best way I can explain it is, it’s not a rough idle but it’s not smooth.
The S10 calls for Iridium, also Bosch doesn't do so well at making spark plugs I have seen many times Bosch plugs failing prematurely actually just had that happen in my Toyota with Bosch, just swapped it out for Denso in my Toyota big difference.Bosch double plat sparks, and i replaced them when i got the truck. it had 128k miles and now has 135k. bought it in April 2020
