i had a similar problem some years back with my 2000 Blzaer. replaced the same items and even went as far as reploacing the distributor assy. turns out that i was getting moisture inside the cap from a crack in it. check ur distributor for cracks or make sure the seal is good on the cap/distributor

When you changed the wires, did you also change the coil to distributor wire? The routing of this wire takes it against a metal bracket, and can damage the insulation causing a misfire.

We're looking for some ideas on the issue that is at hand. Please let me know if you've got any suggestions on this issue.

Here's the thing. Since it has become MUCH colder here, the problem has all but vanished. Ideas?
I chalk it up to being a self healing Chevy, but I'm sure there is a much better, mechanical or electrical explanation.
I hope this will help pinpoint whatever was making it act like it had "pondwater" for fuel.
Oh~ I also quit using WalMart's fuel. Related?
I only bring this up, because I used to drive 60 miles per day, and that is where I would get my gas. (plain unleaded) Then when I got my new job here in town, it sat for months. As I would only drive it now and then, it would have taken a long time to remove the deposits that cheap fuel would leave behind.
Just grasping at straws here...

Thanks for the update. I will let you guys know by this afternoon.
#9 of 13 Blazer Misfire (Multiple cylinder)

My wifes 2000 blazer started to have a pretty noticable misfire in the past couple months. It has a bad hesitation while accelerating around 2000 to 3000 rpms. I first replaced the plugs and wires. Then distributor cap and rotor , the ignition coil, the maf and now the spider injection. Nothing has aided the problem in the least. I was throwing a cel which was the amazing "P0300". I have also looked into any vaccum issues (I have found none). Im wondering if anyone has any input on my issue? Ive been fighting this vehicle and so far its winning.

I was also wondering I have not done a fuel pressure test, could the fuel pump possibly be weak? I was thinking that it may lose pressure when it gets to 2000 rpm due to a weak pump?
