[urq] Running problems

[Ingo Rautenberg]

Thanks, Scott.  I remember and will do, but not sure how soon, as I feel the
flu is knocking on my door :-(

I think the only major hose I haven't replaced yet is the Igloo to IC hose
plus a few smaller ones.  Will definitely delve into the hose area
first....may be time to construct one of them pressurizing thingys....

> Only cuz the old guy told you to do the below.  Ingo, ck the hoses first,
like pull them off and ck them thoroughly.  This really sounds like a air
leak to me, and always did, and it's probably small.  After that, ck the
fuel pressures.  Don't get too far into the ecu quite yet, you aren't onto
that part of the diagnostic yet.  You might also want to ck over your TDC
and rpm signal wires as they route along the firewall.  Worn or frayed, they
can get goofy when hot.

one of our infamous Detroit Potholes, I visited Chicago over the weekend to
wish a certain someone a Happy 45th -- It's always nice when someone is
OLDER than you are ;-). Well, an few hours or so into the 5 hour trip, I get
what feels like an ignition or fuel cutout (nowhere near 4k rpm, btw). So I
just kept plugging along at ~3k, but if I lifted the throttle and pushed
down again she would feel like she was dying and then suddenly grab. Almost
like the intake plate (under the igloo) was sticking. Hmmm. I made it the
~300 miles with a few more stalling incidents where the car would just die
and I'd pull over on the freeway, let it sit for a few minutes and she'd
start up again like nothing was wrong. Would idle OK as well. Anyhow, it got
worse as I almost reached by destination to where I had to jump the fuel
pump directly off the battery instead of the additional relayed connection
at the battery. Tried new ignition switch and checked engine grounds, but
the symptoms persisted. A preliminary check of hoses found nothing obvious.
Later found ground signal was not making it to the underhood fuel pump
relay, so I bypassed that for the trip home last night, but the symptoms
persisted, except she wouldn't idle anymore either then or this am. So she's
parked in the garage right now with the front wheels on ramps. Spark when
cranking is strong. So either intermittent spark, fuel and /or possible
vacuum leak (always that possibility). So do these symptoms sound familiar?
I was thinking of doing cursory fuel pressure checks, recheck all the hoses
and then removing the ECU and checking for cracked/broken solder joints.
