really really appreciate the minds in here, priceless!
Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!
The name "Dielectric grease" is a little deceptive. It's actually an insulator and doesn't conduct electricity.if that gunk inside the iac connector was electrical grease, and i removed it, could a bad connection make the car not fire?
it used to idle at around 1400 coming back from highway, now its at 17-18... probably faulty ioc at this point...
totally makes sense filling up space preventing debris in there, i checked with a charge but didnt notice any movement in the iac unfortunately...
sweet noted!if you applied 12V and ground as directed and didn't see anything - I'd say it's probably dead
Too much air for the fuel. Now that I think about it though, it's all after the MAF sensor, so the air/fuel ratio should still be OK.
Man all a bunch of big brothers in here helping out with our volvos, really precious when issues appear!Excellent for having it fire up. Happy to help and thank you for being cool and genuinely appreciative.
Brickboard faq link below if you don't know about it.
*note: the faq is for 7/9 series but helpful for things like lh and other overlapping systems on 240s *
But I would very much consider really going through the electrical connectors on the drivers side of engine and making sure they are all secure and not corroded, vacuum system too. Starting, then no start after working in engine bay could mean an intermittent electrical problem. I'm guessing you have lh 2.2 or 2.1, what year is your car?
[Double checked and yes the tps and iac connections can be installed on wrong part. with the iac plug having 3 pins and the tps having 2 pins (before lh2.4)]
A few bucks and you can install the stud and nut for the exhaust manifold. Suggest using geniune or high quality. Either way you'll need it so you might luck out and catch it before the exhaust gas blows through the gasket.
Yes getting there i appreciated you confirming the shitty state of wires, my gosh, many were changed but a bunch more are coming, like wooden wires hahaAre you still having problems? Seeing your posts and your note about year and model, the first thing I'd ask is how does your engine wiring harness look? These are notorious for having wiring harness degradation problems. The wiring insulation just degrades(cracks) and falls apart, literally just falls off of the wires. You end up having bare wires touching other bare wires. Good luck!
If you have deteriorating insulation on your wiring harness, the only known fix for all the issues is a complete replacement harness. Dave Barton sells newly manufactured ones.Yes getting there i appreciated you confirming the shitty state of wires, my gosh, many were changed but a bunch more are coming, like wooden wires haha
Dealing with a drowned engine now just gonna clean up sparks and should be good to go.
But YEA! Gonna be addressing all the electrical potential issues
