Re: Re: timing 97 blazer 4.3
Have you check for any codes in your truck. It could be a lot of thinks such as, TPS, trottle position sensor, fuel filter, CAT, and many other things. Check your codes and get back to us with it. Autozone or Advance and many others will check them free of charge. Just don't buy anything if they suggest you need. Get back with us and let us know if there are any codes, I'm absolutely sure this forum can help.
Thanks
Southern.
