So I'm driving on the highway the other day and I hit a bigass bump in the road. There are many of these on this highway (I90/94). Well this one apparently my car did not like. As soon as the bump hit I checked my gauges and sure as ____, my CEL comes on. So I figure there's gotta be only one thing wrong with it, as i've not messed with anything except the intake. So I drive for about half a mile to the nearest exit and stop at a gas station to check out the damage. Thankfully there was no overheating or anything else going on. I looked around the intake and the spot that was being cut into by my frame was fine. So I checked where it connects to the engine, and there it is. My intake rubber seal popped up and landed back down folded over the intake pipe. So my engine was exposed to dirty air for about half a mile. Took me an hour to weasel the rubber back on properly (which was a major PITA since I have a strutbar now in the way). Had to disassemble half the CAI just to maneuver it back in place.

Here's my question. I got a stereo installed recently and so the battery was disconnected (thus resetting the CEL). Now I got the intake back on right, so If there was any other issues with the engine, the CEL would have come back on already right? Is there any reason for me to get this issue checked out at all? And what exactly would they be doing to remedy said problem?

 

After fixing it the CEL should have gone off. If the light is still on or comes back on after a while you might want to check it out, but I doubt there will be any lasting issues.

 

The CEL was because the MAF went screwy when the pipe popped off. I surprised it even let you drive at all. I forgot to tighten the clamp on my intake line once, and when it popped off, the car wouldn't even stay running.
