02 Blazer acceleration problem
Ok, so I changed the muffler but the problem is still there. I have noticed that it kinda feels like the engine either has too much air in the air/fuel mixture or not enough air. I also noticed that when shifting from 1st to 2nd then to 3rd the blazer feels sluggish, but once in third and the tachometer hits 4000 rpms the mixture feels perfect and the blazer runs great. But once I come to a complete stop and then go again the mixture doesn't seem right. Some times it will run fine out of first or second gear though. It is all random. But it does seem like the higher I get the RPMs, then the better the Blazer runs. Any other suggestions? All your help is great. I am not a mechanic so I hope my explanation makes sense to some one here.
