I have a used 2003 1100 Silverado that I purchased in 2005 that has run great until about a year ago when I noticed that it was having a hard time warming up. Now it just stalls when the choke is off. It has a K&N filter and Yamaha custom pipes. I have cleaned the carbs (nothing visible), changed the plugs, cleaned and oiled the filter, changed the fuel filter and checked fuel screens in tank. I know that there must not be enough air flow but I even removed the air filter and still nothing had changed. Running out of ideas.

to cut the long story short
take it to an accredited service center and have the fault codes read
Indicates a problem EVAP system not venting properly and causing pump and fuel pressure problems
If you take it to a mechanic and he doesn't run the fault codes with a scanner first , take it some where else
My 2005 GMC does not have a fuel filter anywhere. Must be another great idea that an engineer came up with." we will tell them not having a filter cuts down on maintainence costs" As far as not having fuel to the engine, I would pull the line loose ane turn the key on to see if you have any fuel flow you might have to cycle the key several times as the pump will only run for 3 seconds with each key cycle, maybe a rubber line has collapsed on the inside, happens on brake lines all the time.
I have had continuous missing issues on my 1997 Silverado after i had a new engine installed 30,000 miles ago. Today I purchased a new gasket for the EGR Valve and removed it. The mechanic had re-used the old gasket when he replaced the engine and cut corners to save $2.00. I found he had installed the EGR bass-ackwards causing my check engine light to stay on and the engine always to miss. Engine runs GREAT now
I too have the same problem on my 2005 1.8t B6. I noticed a hole in the breather hose coming off the valve cover that runs to another port under the intake manifold. I have the hoses on order and should be here on Wednesday. I'll post again if that fixes my problem.
after the bike has warmed up, then reset the idle to approx 1000rpm. then see what happens when its cold. some bikes are cold blooded and the use of choke is necessary for a bit, at least until it warms up...
Hey Don, I understand your frustration! Had the same problem years ago. Sounds like your gas tank is not breathing.Try this: Run the trimmer until it begins to stall out, then loosen the gas cap slightly. The trimmer should begin to run again. If it begins to run, then the gas cap is clogged. Clear the breather hole or purchase new gas cap. This should solve the problem.
