Once was called to retrieve an 84 or so Volvo Turbo that wouldn't start. After cranking a few times got it to fire up and kept running by keeping my foot in it. So had it idling pretty fast, got into drive and made a 4 mile drive back to my work area. Interesting drive, some braking with thortle application. Had to keep the revs up. Next day, found a pretty large hose, a bit bigger than my pinkie had come out of the large runner coming from the intercooler to the Bosch K jetronic paddle type mechanical injection unit. Proved to be an easy fix. But learned that in some instances a spinning turbo can cancel out a pretty, actually really, large vacuum leak. Some lessons learned, really should have probed the car a bit more before bringing it home.

For other S10 owners: I bought a 2003 S10 and those same vacuum lines that Eric replaced were rotted right through and it had a P0442 code which caused the money light to come on. I believe the longer vacuum line from the engine is 7/32, but the two smaller lines are actually 5/32. Add a zip tie around the line to the canister or it will pull off again. I also replaced the gas cap to be safe. My P0442 code hasnt come back yet after clearing it. Hope this comment helps someone!

The salt belt is rough on the old undercarriage. I worked late in Geneseo and headed up 390 to the house in Fairport, when the state cruiser jumped on my bumper and followed me all the way to the thruway. Turns out the company's s10 blazer finally dropped a rusty arm and was throwing sparks on the asphault.

I changed rubber vacuum running same as you on son's 99 last week i did not reset check engine light. I think bigger change when you rechecked because rubber lines colapse in on itself and partially block leak. my son just called said check engine light went off while i was watching video.

Seems silly, it is 2020 and we should have a scanner that connects to the car and self diags and is able to adjust the throttle, etc and give you suggestions.
With access to the internet, it would not take AI a long time to learn and help us.

Does the Autel not have misfire counters then? seems so basic and useful of a feature. which other scan tools do you have which have the misfire counters? (typically mode 6 scan tools have the counters listed)

Probably other Auto Mechanics thumbs you down. Some Mechanics thing if your giving information away, your potentially taking their customers from them and other Mechanics. Anyways, I ran into that in my trade.

When you refer to 'short' and 'long' term, how short is short and how long is long, timewise? I see the long term value changed after only a few seconds of revving up. Just wondering, thanks.

Too technical, the average person does not understand vacuum correction, fuel trim, lean vs rich and the relationship between them. simplify for us layman if you can.
