Greetings guys it's true I sent the engine wash and it was cold, I just could lay his hands on discharge after that, the rpm went crazy,1500/1700/2000 !!! already has more than a week! I see no apparent defect Anyone idea what has happened? Thankful!
We cover every engine bay with a plastic bag when washing. It's good practice especially on older cars.
Everything was very dirty! For it had broken the seals of the joints of the wheels! grease Was flying everywhere!
Do you have to understand that in fact the term to say that she does not like bath this is only figuratively the only problem really came after that fact!
Start the engine and disconnect both connectors of the idle valves. Then connect them. is there any difference? Mormaly the idle valves let the engine idle, but when they stay open (bad connector because of damp or so) then the idle rpm goes way up as you discribe. So first check both that connectors good luck! by the way, it looks like this:
I took my car through a power car spray wash, and a couple of the ECU or Sensor connectors were full of water! I live in Arizona where it's extremely dry, and I don't believe mine would have thoroughly dried out in a week. If you live in a more wet climate, I still think you could have water in connectors. It's easy to disconnect them and check. Of course, it's up to you!
To the guys who would know better than I...(pretty much all of you) Is this the kind of symptom you might expect from a cam sensor problem?
I haven't actually washed my car in over a year, only dusting and spray on detailing. Of course if I'm caught in the rain there's nothing I can do, but a hot engine and a moving car should resist some amount of water getting into sensors. I doubt if anything broke, since it happened after the wash I would still suspect water seeped into a connection and is still there.
Was the engine sprayed underneath? If so, I'd guess that the crankshaft sensors (or their connectors) is the problem. It's possible that one or more of your spark plug holes are full of water. Have you pulled the wires off the plugs to check down by the extensions? If water gets in there, it won't dry up for a LONG time unless you blow them out with compressed air.
Hi Jeff! Well, anyway, she will spend a few days out of use! My engine is full of small oil leaks! Although only 43,000 Klm wheelsets She was left to chance for a few years by the former owner! and to dismantle it, if you really infiltrated water, will allow time to dry! this to me 2 years poor live in one of the most underserved regions of Brazil to specialized workshops do not help! you has been of immense value! a good workshop for assistance only in about 2500 Klm! Just being very passionate about Ferrari!, because having one where you live is a huge headache! Well, I'm making a list of equipment needed to solve the leaks I think we'll find the best prices on RICANBIAMERICA agree?
This would appear like an obvious electrical issue, given the circumstances involved. It's not just the water, but the corrosion that goes along with the water. Over the 20 years I had my 348 I remember this happening a couple of times. I dried and cleaned all the connections, and used dielectric grease to cover the connections, and I bet you will be good to go.
That's what I say Dino! until I find out where ... patience!... on the grease, do not know where I could purchase?
Was this answer not what you wanted to hear? If the idlespeed is not correct it seems logically to start withe the idle-actuators, doesn't it? There is no camsensor and if so it wouldnt affect idle. Water in a spark plug hole wouldnt cause the engine to idle 2000rpm. And bad connectors, sure! Its possible but there are hunderds and we dont like guessing (thats why Las Vegas is in the USA and not in Holland )
Yes, there is a cam sensor. And I wasn't suggesting that water in the spark plug hole would cause his high idle, I was suggesting that water in the spark plug hole could cause a misfire (particularly after spraying the engine with water), and the misfire could cause the Motronic ECU to send a false signal to the idle stabilizer to attempt to compensate for it.
Yeah, and what do you do when you forget to take the plastic bag off before the next drive and it melts all over the engine?
