Default help me locate the Intake Manifold Gasket...

My car has a rough idle and is throwing the P0301 (cylinder 1 misfire) and P0507 (high idle) codes.

After searching around on the forums, I've concluded that I need to do a vacuum leak test with carb cleaner.

I'm not sure exactly where to spray this stuff. Can someone help me out?

One is the Intake Manifold. Two is the Throttle Body.

If you locate the valve cover, it's the top of the engine, which will say Saturn on it, and have a few rubber hoses coming out of it. Behind that is the intake manifold, which is metal and runs side to side, with 4 metal tubes running down from it to the engine. Where those tubes meet the engine is where your intake manifold gasket is.

Use this to help you out. If it turns out to be the intake manifold is leaking; continue further down into the thread. You will see where I posted the "how-to" on fixing the gasket, provided by RC1488.

Thanks a lot. I'm hoping to solve this 8-month mystery and everybody on here has pretty much been my lifeline throughout this process.

UPDATE: I sprayed the intake manifold. When I sprayed it on the one 2nd to the left, the RPM's dropped and the engine shook and almost stalled. I could see the cleaner fizzing out of the port that I was spraying it in.

Now that I've detected the vacuum leak... I can assume that what is wrong with it is a defective Intake Manifold Gasket?

Annoying, isn't it. I just finished replacing mine in 4 hours...3 if you don't include the time futzing with the belt and block coolant drain.

I did it similar to RC and the literature way...guess I kind of molded them together. I did it all from above the engine. Note, you will need to remove the fuel rail in order to get the torque wrench in there, and I found a set of SK semi-deep sockets at tooltopia.com for ~$55 ($75 at Sears) that will fit perfectly over the studs to the nuts, but not stick out so far that you can't get a wrench on them. I pulled the power steering off and set it to the side which allowed me nice access to the hidden nut right underneath cylinder #1. With all that, I still wasn't able to use the torque wrench on the middle three nuts, but they should be pretty close to the spec'ed 22 ft-lb torque with my ratchet (felt the torqued one first and matched). Although, I could definitely see someone not being able to do it my way if they have big hands or arms...I'm just a little guy in that department.

I wouldn't mess with the block drain plug, they really torqued the hell out of it. Just drain it through the thermostat housing (I'm replacing that too today), I think I might have started rounding that trying to get it off .

Go from the bottom. Its easier. No need to remove the fuel rail.

No need to remove the power steering pump. Just push it out of the way.

The block drain plug is a 10mm 6pt bolt. Its not torqued tight at all. Just need a long extension to get to it with a 6 pt socket. NOT a 12 pt.

Glad you got it replaced

I'm only saying that I needed to remove the fuel rail in order to get it torqued right. Otherwise I would have definitely left it right where it was.

I was using a 6 pt 10 mm socket with a 6" extension and 17" breaker bar. It didn't budge. It felt like it was starting to round off, so I stopped. I don't know why it's so tight, but it worked out alright in the end. I might have gotten it off axis with the length, I'm not sure. I just didn't want to FUBR the plug.

It was actually necessary for me to do it all from above, as I can't safely get the car up in the air at my apartment to get under it...and I'm on a somewhat limited income until I can find a job (anyone looking for a MS chemist/ultrafast laser specialist? I'm available!). Ramps (which I would prefer) take up too much room, and stands make me nervous. It worked out in the end.

In all, I spent about a month planning my replacement so that it went as smoothly as it could. It seems I should have spent more time thinking about the thermostat replacement!
