2 weeks ago i traded my 2004 dodge neon with 75,000 on it, for a 2000 blazer 4x4 with 125,000 miles on it. So needless to say, i also traded my dodgeforum membership for a blazerforums memberships.


when i traded vehicles, i new what my little car was capable of. It had a zex cam, K&n intake, header & highflow cat, and muffler. It was really reliable.
I have no idea how this blazer was treated before i got it. Ive baught new tires, plugs & wires, shocks, flowmaster & K&n, and have changed oil & rear diff fluid all in the past 2 weeks. I need to change tranny fluid & t-case fluid.
This blazer has a vortec, i know chevy is reliable, but since it has 125,000 miles how many more reliable miles should i expect from it?

for the most part, it runs good.....but every now and again when i hit 3500 rpms it seems like it misfires or something. not sure what could be causing it. any advice would be appreciated

 

I also have a 2000 and mine has about 260000 kilometers (im not sure how many miles that is) the engine runs great a little loud sometimes nothing scary.

 

For the miss I would try cleaning the MAF sensor and while you're doing the wires it may be a good time to change out distributor cap/rotor. Who knows when they were changed last? That took care of my low RPM stumble and it feels like it's running on 6 cylinders now.

Mine is also a 2000 4x4. 146,000 miles.
