Re: Idle surge/stalling
About 3 weeks ago I wrote about my 87 5KTQ stalling when hot and A/C on. As
always I thank you for your resposes and help. It seems to me that certain
parts fail on these cars as a factor of time and not mileage but I would need
to research that point, i.e. alot of posts on 87 idling, brakes, Bombs, etc -
we can't all have the same mileage.
Anyway - my results:
Cleaned air box and plate = no change
Sprayed ether = no change (remember I never claimed I was perfect)
Inspected hoses - appeared OK LOOKED CLOSER - crankcase breather hose on
verge of collapse, big hole on underside, another breather hose (?) -shaped
like a crooked "J" smaller hole, also soft as gel. Took off the large hose in
front of engine on turbo inlet(?) - has wire around it- found small 1/4"
After replacement, idle just stayed high, I then was able to turn in the
brass metering screw and achieve a normal idle. NO surging, no stalling.
Mileage jumped instantly and my boosst which was just making 1.0 to 1.1 now
I hope this helps those of you with similar problems.
This weekend, we change the bomb.
Funny, I saw this movie with Tom Hanks called the "Money Pit"......
