I followed spike's steps to clean the throttle body on my 03 discovery, and after I started her up she sputtered like he said she would, and while I was driving around the block, the service engine light came on...any ideas? Will this light turn off or what do I need to do??

 

You need to rent or buy an ODB-II scanner and erase the codes. They may or may not turn off on their own depending what they are.

 

Is this a typical problem to have after cleaning the throttle body? And no one knows if this light will go off by itself?

 

Yes it is normal because you in essence flooded your engine while you were cleaning the throttle body. And no one knows if the codes will go away because no one knows the exact codes you got. Autozone will read them for free but they will not erase them. So you can drive around for a week and maybe they will go away or just rent a scanner or borrow one from someone and clear them in 20 seconds.

 

Yep, like lipadj46 said, the SES is normal to come up. Mine was throwing codes when I cleaned my throttle body and Seafoam treatment.

Did you did a seafoam treatment?

 

no, i hadnt gotten there yet...so im going to have to get a code reader to clear it out? i dont have an autozone around me, haha, i am out in Montana

 

If i do need to get a code reader, anyone have any suggestions about a good one to get for cheap? haha, also, living out in Montana I was wondering if anyone had any experience with block heaters?

 

Mine came on after I cleaned the throttle body and went off after 2 tanks of gas.

 

Harbor Freight has them cheap ~$50. If you plan on DIYing you should at least buy a basic scanner that reads and clears codes. It is just a useful tool to have. I believe Spike555 bought a good scanner off of ebay that also reads live data for $60.

 

Don't go wasting your money just yet. It is possible to have a code come on when doing the induction cleaning, and if after driving it, it runs smooth, wait a couple of days cause there is a good chance it will go off by it self, usually after 5 or 10 start cycles. If it doesn't, then go ask to get it cleared. It should not come on when doing a t/body cleaning, unless you try cleaning while the engine is running which is not the way to do it.
