Sea foam throttle body spray works great.

 Would Recommend

I have a 1994 chevy s10 blazer 4.3l. I have been working on this for weeks dealing with a misfire, even had a mobile mechanic look at it. I found this sea foam spray you actually spray right into the throttle body. I couldn't believe it worked perfectly, the car runs great, I just wish I had known about this stuff a long time ago. I am going to buy more of this as soon as the store restocks
