Thanks Peter,
I'll take a look - so far I have not found any of the hoses to be hard
with age. The PO had many hoses in the engine compartment replaced not long
before I bought it. He was chasing a problem I solved with long-distance
driving. So, I may still have a loose hose - I could have knocked it off or
perhaps it fell off.
Thanks for the suggestions - I have a better idea about what to look
for.
Have been reading the Shop Manual section 07.1 that deals with he ELR system
(Electronic Idle Speed Controller) and I really hope it's a loose hose as
some of the various devices have expensive sounding names. Things like the
Flywheel Engine Speed Sensor and ELR actuator, etc. Re-attaching a hose
starts looking attractive pretty fast. ;-)
Thanks again for the help -

Larry:
It's under the air filter housing up front, about half the size of a
coke can, two wire connecter on the fore end and two large rubber hoses
on the aft.
Hoses are likely rock hard leaking. If the one from under the air flow
meter horn (what the air filter housing goes on) pulls out from the
rubber boot, you need boot, hoses, injector seals, and probably seals
for the injector holders.
Just did all the above except the holder seals, that's this weekend.
Cured the rough idle, hard starts hot, stalling, and noise at cruise.
Peter
