Sup everyone and welcome back to the channel! Very simple today, lots of freakin oil changes... lets go! Thanks so much for watching, liking and subscribing!!
"You know what doesn't have coolant in it?" The Transmission! 😆💯 As for the Idle surge on the Prelude. It could be the Fast idle thermo valve. Here is what I would do to rule that out being the issue. Make a block off plate out of some cardboard laying around and bolt it back on to block off the ports. If the idle returns to normal then its the FITV causing the surging idle. If you find out the FITV is the problem. Take the FITV off of the throttle body. Remove the cover that has the valve and inspect the little threaded plastic part inside that has the spring in the middle. Sometimes they can back themselves out and come loose. If that is the case tighten it back up and you are good to go. It doesn't hurt to clean it all out with some parts cleaner also. Sometimes carbon build up and cause the valve to not work properly. It could also be the Electronic Air Control Valve. Especially if its throwing a Code 14. Make sure the coolant lines are not leaking first off. Second take a ohm meter and check the resistance on the EACV. The resistance should be between 8 and 15 ohms. If it has more or less than that replace it. Clear the codes and test drive and see if the idle is normal and doesn't throw anymore codes. Third check to see if the PCV vavle on the intake it sticking. If it is it can let more air into the intake manifold causing idle surging. If those three things do not fix it let me know! We will figure this out brutha! 😆🤟 Cheers Dan!
You are the man, can't wait to try all of these! Next time it throws the code I'll double check it, and the EACV looks new but that doesn't mean it's working properly.. Great to know the resistance numbers so I'll check tomorrow 😁 I've always thought the PCV valve looked a little weird on the prelude, is it something internal that moves up and down or opens/closes? How exactly would it stick? Either way I'll either comment back here or shoot you an email. Thanks homie!
@@DanWithTheWrench No problem at all man! Yeah the PCV should be able open and close freely while being able to seal when it closes. They can clog with Oil sludge and carbon build up over time or the little valve inside stops sealing. Then it can cause a vacuum leak like condition due to excessive or restricted flow rate. They are really cheap to replace so if you have not done it in a while I would pick one up from the autoparts store and replace it to rule that out being the issue.
