You need to provide some basic info about your car. Why not add a "signature" with year, model, engine, tranny and any major mods. That way it will be easier for people to respond to your questions.

Have you scanned it for codes? You indicate you "took of my intake".... do you mean you removed the ducting from the air filter to the MAF sensor? Or did you also unplug the MAF sensor?

Do not start multiple threads on the same problem. Post it once, and wait for an answer. You can push the thread back to the top AFTER 24 hours.

Well to start you have to give way more information to get good answers. What [EDIT] you have given so far has got you poor [EDIT]answers.

Tell everything start to finish and try to make it so people can figure out your issues. Then you will get some real help

You need to answer the questions that people ask. What parts are you talking about when you say "the intake"? Does that include unplugging and removing the MAF sensor?

Helpful Hint: To add a signature, you don't just space a new sentence down 10 lines. You left click on "USER CP" on the red tool bar at the top of the page, and click on "Edit Signature" on the drop down. That way, you "signature" is always added at the bottom of your post, without having to type it in every new post.
