I have 2 questions reguarding my chevy 98 blazer that I hope you can help me out with. First of all the RPM is very low. I have already performed all the rutine tune-up, but that didnt seem to help. And my second question is when i start the truck and i've waited for it to mark that the engine is at least 1/4 of the way hot enough, and i get it moving at first it will shake, wobble, and pull a little while i press the pedal.It will continue to do this untill i get to at least 45 MPH. It will stop doing it once i make a complete stop, but when it runs again it will start all over again. This will continue to go on untill the engine marks that its at the correct temperature 1/2 way down. Im hoping you could help me figure out what it could be, and if it could be more serious.

It sounds like it could be a few things. Has the check engine light come on? Have you checked the catylatic converter to make sure it isn't partially plugged?

Let me know

That was my initiall concern there was no check engine light on, but i went to get it checked anyway and they said that the check engine light had been erased. Now i have just bought it, and the guy that sold it to me said there was no problem it just needed a tune up. But now that I went to get it checked out they said it might be one of three; the spark plug cables, the spark plugs, or the injectors. Now as i said before i just did the tune up so i dont think spark plug is the problem, and the cables... I had a problem with these with my dodge truck a while ago but i really dont think its that. So im leaning more to it being the injectors. Would you say i have a good chance of it being the injectors or more to it being one of the others?
