Also, fyi, I didn't have an eml before I did the intake...did that for cooling system hard pipes. I got the eml because in wrapping things up, I forgot to plug back in a few things...Round plug (thought that was icv, not TB...but guess you're right)...the oil pressure sensor on ofh...and also the temp sensor...and I think I forgot one plug back by the driver...forget which one it was.

Get an inspection mirror and 100 lumen flashlight (or thereabouts) if you don't have those things...and start by just looking. It's hard to see the vac hoses behind the intake mani, but getting off the cabin air filter housing is very easy...ditto air box.

I can't see that that one broken stud is leading to a large enough leak that it would trigger eml. I think some electronic thing is unplugged...

Vanos solenoid maybe? Remember, you unplugged a lot of crap to remove that thing.

You could carefully spritz short blasts of carb cleaner by the likely sources of leaks. Your wife doesn't have to keep it running. If the engine spurts up where you spray, there's your leak...if your issue is a leak, that is.

I think you're going to find an unplugged connector. Sorry!
Same here - no EML before this little project. I have the mirror; though I found today that a good flashlight would be very helpful as it's very dark under there.

I was so careful taking everything off that I can't imagine it being a plug. Each plug I taped with masking tape and labeled it. Unless there is one I missed by the engine block.

Just returned from Auto Discount and got carb cleaner. I'll give that a try tomorrow first. And if no leaks I'll start pulling everything apart to see if I missed a plug tomorrow.

As far as the fasteners for the plugs on the injectors - is there an easy way to put them on. I tried the first one quickly and it seemed almost impossible.


I appreciate all your help. I feel like I'm stranded on an island without my car.

I have some very good news to report today! Last night when I purchased the carb cleaner I also got a can of dry gas and put it in as soon as I got home. The car has been sitting for about 8 months. (Long story short we had a truck that we sold recently specifically to get this car up and running) This morning I went out there with my carb cleaner to eliminate vacuum leaks. Started the car and it started right up nice and smooth - No EML!! Then it started running rough again. It was just the boot that connects directly to the MAS. I clamped that down good and she is running so much better!

Though there are still some problems, but I have faith that they are little ones. The check engine light is still on. Though I'm not to concerned. The one thing I am noticing is that sometimes I feel a click or popping on the gas pedal and one on the engine. I know when I cleaned the TB I did a quick job and it was still sticking sometimes. And also I'm not 100% sure I reinstalled the throttle cable correctly. Either way I figure they are not that major of problems. At least as far as cost or time to fix.

And the one last thing that I haven't done yet is put the clips on the injector plugs (Wire harness) - There must be some kind of trick to that because it looks very time consuming.

As I recall with the injector clips...just pull the rail up, put the clips on the 'rail' that has the injector connectors on them...then push it down. The clips will click into place. Easy peasy!

Glad you found the problem...and hope you figure out your CEL. If you haven't cleared codes, that might disappear after the car gets used to running without a major leak.

GL!

I didn't come back in to read the above post until after I had been trying to get them on for a good hour! After I read this post I went back out and they went on with out a hitch. If only I knew.

And you were also right about the missing bolt not causing a vacuum leak. I cleaned the MAS this morning very very good and the EML light came off afterwards. Though, the DSC light has seemed to stay on along with the service engine light.

I'm not that worried about the service engine light because I know I need to get new garments for the valve cover gasket. There is oil getting to the spark plugs and I'm fairly sure that is whats causing the check engine.

As far as the DSC light ... I'm thinking it could be because one of the connectors isn't making a good connection and needs cleaning or possibly the MAS still?


Anyways the car is running much much better today. It revs up without issue and has power. Still have a lot of work to do, but the biggest problems I think are in the past!

Thanks again.

For some reason, I'm recalling a post yesterday that surprised me about someone having eml, dsc, and brake light on...and I think it was a bad throttle body...I think that's what I heard.

That round connection gives folks problems too...but if you haven't cleaned it, I wonder if maybe it's hanging up. That's speculation...so I shouldn't have said anything. I know you have different lights.

Have you done a thread title search for all your lights yet...I'm sure you're not the first to have them all. I'm not sure if you meant your eml light is on or off...but the way you wrote it makes me think it's on still.

Next step is the 100%, no holds barred jfojing of your car...getting rid of anything aftermarket...painting it green. Fern Green.

Right now it's only the dsc and service engine. The brakes light was never on for my car. Plus, I think you're are right about the round connection. The first chance I get I'm going clean it. Well maybe not the first chance. I need a brake. Feel like I've been living under the hood.

Now for my next project ... 100%, no holds barred jfojing on my car...getting rid of anything aftermarket...painting it green. Fern Green (in photoshop)
