Hopefully someone can help me. I have a 1998 s-10 Chevy Blazer. Over
the past two months it has been acting up for me very sparatically.
Sometimes it stalls, sometimes as I am accelerating it stops
accelerating and backfires as I push on the gas, and sometimes it just
deaccelerates on its own. I have had it in the shop for a total of 4
weeks. Problem is they can’t get it to act up often enough to test
it. The one code they pulled was that it was too lean... which led
them to believe it has to do with fuel control. They started to only
see it act up when the fuel level was very low. Well I have kept the
tank above a half tank for the past week and it still acts up at high
fuel levels. Does anyone have any ideas of what I can do or what the
problem could be? The auto shop mentioned baffles in the fuel tank
and fuel pump- but again they thought the problem occured just with
low fuel levels and that is not the case.

I've been pretty scarce around here for the past year or so; got back into
nitro r/c this past spring and have been spending more time wrenching and
racing my "little trucks" than the big ones. It's starting to get cold
outside, so looks like I'll be searching for a few winter projects to keep
me busy. I'm thinking about building a SPAD (simple plastic aircraft
design) or two or four over the winter to get me ready for spring. Pretty
nifty things, built using corrugated plastic (like beer and pop signs that
are hung in convenience store windows) and yard sticks for the wings, and
either aluminum downspout or c-channel aluminum for the fuselage. Should be
fun, and should keep my other winter hobby (drinking Jim Beam) in check!
I haven't heard of that before, but it sounds like fun. I've got a Super
Sportster 60 in the basement that hasn't been flown in 4 or 5 years. I'm
going to have to find time to fly it again, always something going on
though. If you get one of those SPADs flying I'd like to see a picture.
While a new fuel filter isn't a bad idea, dropping the tank to replace a
$700 fuel pump because it "might" be bad... blowing out fuel lines
because... I don't know..... they're contaminated with fuel? We have no
reason to believe anything else. And the thought that a loose fuel tank
baffle could cause the problem is absurd given the information we have.
Intermittent problems can be a bitch, no question about it. But throwing
parts at it seldom solve the problem.
