Just a quick question.. it seems sometimes when im driving/taking off it seems to spit a bit like it will be fine and all of a sudden it will just spit/putt for a few seconds then be fine again.. any ideas what it could be?

 

plugs/wires/fuel filter are the first things to check when this particular issue happens... What's the mileage? You might be able to rule out the wires that way...

Has it just started recently? Could be a bad tank of gas...

 

128 000km

Its been doing it for a bit.

 

Try changing the fuel filter first... The filter itself is fairly cheap, and was easy to change on my old Lumina, don't know about the Blazer's yet, lol, but should be easy enough to do, if you've got a Haynes manual, or similar, it'll help...

Plugs & fuel filter first, then if it still does it, we start digging deeper, lol.

When were the plugs last changed? Might be able to get away with doing one or the other if you're strapped for maintenance cash, but better to get 'em both done...

 

Im pretty sure its time for plugs to be changed. Ill do both. How much do filters usually run?

 

Any other things you guys can think of?

 

I generally buy AC Delco filters for everything, and they've all cost me less than $10, and generally less than $5... Just don't buy them at the stealership, lol

 

Im gonna do cap and rotor as well.
