Need help with my 345LE Engine!

Hi All! We just picked up our first Airstream -- a 1989 350LE! We are very excited, but there is one little problem. The engine starts fine, but when we start accellerating it chokes and stalls. Yesterday this went on for about an hour (we are in the process of driving her home to CT -- and had her in the right lane with hazards flashing), and then suddenly everything was fine -- she drove like a dream for 200 miles. Any thoughts on what the problem might be or how we can fix it? Thanks so much!

See this thread -

On some units the wiring to the fuel pump is fed through an oil pressure switch, so, if the engine is NOT running, no voltage will be evident at the fuel pump (the switch is (oil) pressure activated).

Is it still running fine? Maybe something got clogged in the fuel filters?? or in the previous post fuel pump?? but seems like some type of fuel or lack of fuel issue.

As with all things old, the probable cause of your problem is most likely from multiple system malfunctions, keep at it, repair/replace the old stuff, and eventually you will have a dependable ride. The best thing about self-repair is that you will be able to recognize and repair future failures in short order, either on the road or at your home base.

Just wondering - I did not think that AS made a 350 in '89 - just the 190, 290, 325, 345, and 370.

If you have the 370, you are in an entirely different environment than the rest of the models. The 370 was set on a Gillig chassis with a Ford drivetrain - I have a friend who purchased one of these new and has a multistate horror story of a long line of breakdowns.

There is MUCH more info here on the Chevy 454 than the Ford 460 drivetrain.

Put some "Heet" in the fuel tank. Sounds like water in the fuel.

There should be an inlet filter at the carberator/Fuel injection unit. There is also a canister type in-line filter located on the inboard side of the curb side frame rail just ahead of the cabin step.
Our 345 does not have the rear electric fuel pump. If your 350 has the rear pump, there is also a filter near it.
There is also an in-line filter for the Generator. (In the Gen bay)
Hope this helps, and welcome to the group!
Driving an Airstream Motorhome is the only way to go!
