It stumbles off idle, but above idle runs normal. no appearant vacuum hose issues. What is a good source of refference for all the vacuum stuff under this hood?

Thanks

wen wus the last time u changed the fuel filter?, it could be clogged!, sounds like a fuel system problem so chk dat out n lemme kno.

 

We will try that this weekend and I will post what we find out.

Thanks for the input.

I would look at the MAP sensor for problems. It monitors the vacuum in the intake manifold, and varies the fuel profile based upon load. When you step on the gas pedal, the air can flow RIGHT NOW, while the fuel, being more dense, takes a bit longer to accelerate and catch up with the air. To handle that, the fuel flow is bumped for a bit, how much I don't know, but it is some part of a second or so that the mix must be enriched to keep from stumbling. If you have a MAF, that would be the basic same thing to check for the same reason.

Thanks for the input - heading over to try them out now - will update soon

Thanks again

Grumpy here,
This little thing has vaccum hoses going everywhere! They look in decent shape, Where is this MAP sensor? I am expecting a plastic device with wires going to it mounted on the intake, I do not see it -Help.


Is there a port to check fuel pressure?

Thanks.
