I had an AEM CAI installed a few days ago, left my buddies house and drove home, about 60km's from his place to mine. On my way home I didn't run into any problems, car ran smooth. Had the car in the garage for 2 days after and finally took her out tonight for a little spin. I let the car warm up and then drove away.

About 2 min from my place I get on a stretch of road and decide to punch it, wanting to hear vtec again. As I get higher in the RPM's about 4-5k the car starts to bog and buck, just a little though kind of sputtering, and then once in vtec it was smooth. My CEL comes on and starts flashing, then all of a sudden it's gone and doesn't return?? Should I be concerened?

I drove around for atleast another hour to see if it would return or start sputtering again but nothing. I gave it a few times after and no CEL came on.

Anyone know what might have happened?

Did the temp gauge reach "3 bars"? If not, you hit the cold rev limiter. If is was "really" warmed up, then suspect the MAP sensor. Honda has a TSB for this.

You might also have your vacuum lines reversed. Check those, too.

Crossed vacuum lines would generally sustain a CEL once it comes on, but you never know. It could also be a backwards check valve, which takes a bit longer to generate a CEL and may not initially stay on (the first time). What's scary is that the CEL "flashed". This usually means a severe misfire is happening, although it was momentary. If this is the case, even with the CEL off, it may still be possible to pull the code.

Temp was 3 bars before I left my house lane way. I thought it may be the MAP sensor but tough for me to tell.

If my lines were indeed crossed, would it not have done this on the way home from my buddies house?

It was weird because it didn't start sputtering until I hit it, and then it went away quickly as the light was blinking. As I got into vtec more 7-8k the light simply went away. It almost seems that the final blink was a half blink and then never returned.

Again I drove around after this light was on, and nothing ever happened.

Not necessarily. Read my last post.

Good to know. I'll check them tonight. Could you tell me where these lines are located? Im not to engine savy as you can tell.

Thanks for your help.
