ok, I bought a 94 accord lx with a blown headgasket, so I put a head gasket it, put it back in time and everything(according to a write up on this forum-thankyou) and it starts up, but it idles up to 4000 and the sounds like it shuts off, but idle picks up at 1000 and rides right up to 4000 again--- I'm freaking lost..... does the car need to have coolant in it to idle?

 

Why would you start your car without coolant? That's asking for disaster.

 

LOL seriously. Coolant is your friend. It's like turning on your computer without anything to cool it. Or running your car without oil. Or when you're in the bed and you don't use... NVM, i won't get into that.

The coolant helps warm up the incoming air. More like an intercooler cool the air for a turbo car. Making the car warm up faster.

Dude, what? NO. The objective of coolant is not to warm up the incoming air.....and cooler air through the intake gives you more power anyways. What the <U>cool</u>ant does is prevent the engine from overheating, thus cooling it. The coolant is pumped through the jackets in the engine, then it continues back to the radiator where the heat is diffused out of the coolant, and it continues on this cycle, thus preventing your engine from heating to astronomical temperatures and melting into a lump. And intercoolers don't cool the air for the engine....they also help cool the engine because a radiator is not sufficient for turbo setups. Man I'm glad you didn't include the bed example because I'm pretty sure you were about to say strap-on, giving information like that.

 

I was just starting the car to make sure it ran properly before I put all of the belts etc. on.... and I guess it was a good thing I did, or I would have waisted alot of time... does anyone have any advice? or could someone tell me the purpose of oil also?

 

Oh jeez. If you want to know how the engine is going to run when it's hooked up to everything, you have to actually hook it up. You can't drop it in there, connect the battery and fuel lines and starter and fire it up. Newer cars have an ECU, basically a computer that measures many different sensors, controlls the air/fuel mixture that's injected, and sets off the check engine light if there is something wrong with the engine.
The purpose of oil is to keep all the internal parts of the engine that move around lubricated. All the movement at several thousand revolutions per minute generates a lot of friction, and a lot of heat. That's why you need coolant, to keep the engine from getting too hot, and oil reduces the friction between the moving parts so that they don't heat up and break. Did you start the engine without oil in it too?

 

In your case, the first place to start may be with the gaskets -- between the intake manifold and the block and between the intake manifold and the air chamber. You can buy those at Autozone, etc.

Check also the placement of all the vacuum hoses.

After that:
idle air intake valve, fast idle valve, throttle position sensor, and the MAP sensor, including their gaskets.

.....the purpose of oil is to lubricate the engine basically. It stops the metal on metal contact so you don't sieze things together or cause absurd amounts of ware to the different internal parts. Also it helps everything move smoother and lubricate, also takes some heat out too. I dunno thats the basics of it lots more to it

^^^ all about oil and such go read its good. enjoy

Dude I don't want to be an *** but did you even read my post? I can appreciate the web link, but everything else was just restating what I already said.

 

well then i just read it agian, i guess it didn't really register in my mind, i saw those words but nothing clicked, my bad

 

Haha, no worries, I guess it doesn't hurt to repost, with the hopes that maybe some car knowledge will get pounded into the OP's head.

 

yeah check your intake manifold gasket first, thats what mines was on my lude...after i bough a fitv and a aicv for abotu 500 bucks. then all it was a a 10 gasket...lol
