Here's one for the experts.

My engine light is on but everything seems fine.
I disconnected the battery and it goes out for one start and run. As soon as I restart the engine a second time it comes on.

The only symptom is low torque and rough running at idle to about 2,000 RPM. After that it is strong and peppy.

Before I take it in to the shop, any ideas?

Two things to check. Make sure your gas cap is on correctly and check to see if your engine cover is properly installed.

 

Now, thats interesting. The gas cap ain't it. I know that problem.

My engine cover was off for 1,500 miles before this showed. Never heard that one. But I will investigate.

Problem is my CAI won't let me replace it.

So, now what?

roadster with a stick.

 

There are no snsors on the cover.

Get a code reader and see what is going on. Only way to be sure.

 

Yes get a code reader or go to Autozone have have it scanned for free. There is something wrong that needs to be fixed. I don't really believe in using the battery diconnect as that is like trying to ignore a problem. If the light comes on you want to know why and take care of it. If you get the code we can hlep you you fix it.

 

Yep, Thanks. I'll stop lookin'

Don't need a code reader, my friend at the shop has one. And while he will charge me to do it, he has the time and tools to fix it.

I don't.

That said, I would still like a clue about what it might be. Once I really, actually retire and have the time, I will have to do it myself anyway.

Probably a small vacuum leak. Check all the hoses and sensors on the front of the manifold and listen for any hissing coming from the edges of the manifold.

My engine has a nasty leak that has the engine idle at 1500 rpm. I sort of broke one of the vacuum connectors off of a sensor, so I know where my problem lies.
