: Flashing Check Engine Light

Hey guys, its me, Skip, again. So I was driving my car around today for a little joyride, when all of a sudden, my car shook violently and there was a loud boom. Ever since then, my check engine light has been flashing and my car sputters badly. It sounds like its about to explode when I go into VTEC.

What should I do?

When he "goes into VTEC" makes sense. I hear a lot of people say that or when they "hit VTEC". VTEC isn't active at every RPM, only above a certain RPM. The cpu senses when the car is at full throttle (or at least heavy throttle) and above that certain RPM (not sure exactly what RPM that is: JDMCivic might be able to tell you) and it increases the valve timing and lift to create more power. It also makes a "meaner" :mad: engine note!!!Same thing as Ecotec, VVT, etc.

P.S. Not sure if I'm 100% correct but Im sure JDMCivic could clean it up if I have any mistakes, Im pretty sure thats the general idea though.

action, have you noticed it being louder than normal under normal driving conditoins? Could be an exhaust leak or somethin... Dont know why it would have banged though. Maybe it backfired. But I dont think that would explain the vibrations.

Dude when my vtec hit in my cavi it was at like 5500rpms and it stayed till redline which was like 9500rpms!

That might be a backfire. And is the shakeing all the time or is it off and on and is it only during acceleration or deceleration or idle. Sorry for all of the questions i have alot of freinds who know alot about Honda's and Acura's. Plus i know alot of auto mecanics.

I hope you're not one of those fake RSX owners trying to make us look bad. I don't know why you'd be asking on THIS site... Anyway, if this is truly happening, bring it into the dealer and they'll pull the engine OBD-II code for you (likely for a price). I don't know if you're out of your warantee period yet but get it checked out.

Also, it helps to know what you did prior to this happening. It also might help to "reset" your ECU but this doesn't. You can't simply disconnect the battery. I think you've got to find the right fuse to pull. What kind of gas did you put in? Did you overrev when downshifting? Did you have a tune-up or bring it in for maintenance lately? Maybe a sparkplug's not firing? I'm not even going to speculate on what happened. Get it checked out.

The RSX-S enters VTEC (no H) at 5800 RPM. It leaves VTEC at 5600 RPM. VTEC is just Honda's way of saying variable valve timing. It uses different cam lobes in VTEC. Essentially, it's entering performance mode.

If your CEL is flashing, you usually have a misfire. It also means you are punishing your cat and o2 sensors.

Don't drive it with the flashing cel, and definitely don't engage VTEC. Stress on cat and o2 sensors plus added stress from VTEC isn't a good combination.

Try to get it to someone that can scan your OBD-II. If the CEL is blinking, don't rag on your car.

Thanks for the confidence in me. Unfortunately I have no idea what's going on. I gave a few suggestions of stuff to look at or think about. We don't know the whole story plus this is something the dealer will need to look at anyway. Sounds pretty serious.

It's still worth a shot. You can't be afraid to ask questions. The worst someone could say, is "SEARCH!!!" but your situation sounds pretty unique.

OBD-II covers 3 different diagnostic protocols. Same connector is used to grab your OBD-II data. All cars made in and after 1996 have OBD-II. Means you can go to most tune-up places and they can tell you what the computer believes is wrong. See this (http://www.obdii.com/) site for more info.

I had a buddy with an Integra that had this EXACT issue. He had to get some pretty extensive work done on the head in his case. I'm trying to remember what it was, something about the mechanism that switches lobes? That sound possible to you guys? He had to have something removed and replaced that controled either the cams physical switch over, or the electronical switch over. Same thing though, he would run to VTEC and the car would all of a sudden stall, sputter, you name it HUGE backfire when I was in the car with him. Either way, it was leased and the dealership fixed it that time, but they had the car for almost 2 weeks. Three weeks later his timing belt snapped and did even more damage to the system, they ended up replacing the whole upper 1/2 of the engine almost. Two months later it was repossesed! Some people have all the luck.

You're welcome.

Most cars beyond 1996 are OBD2. For instance, early 1996 VW Jettas were still OBD1. From June 1996 on, they became obd2. Newer MkIV Jetta's use their own diagnostics system, the VAG-COM.

ActionJackson, OBD-II stands for "On-Board Diagnostics 2". OBD0 cars had a light that blinked. The number of blinks it made represented an error code. OBD1 cars had to be "jumped" before the light would flash the code. OBD2 cars have a plug that a special computer can be plugged into to determine the problem. They are more extensive than the older systems, unfortunately, they're less appreciative of mods too.

Get the code(s) scaned and tell us what it says. It will be a letter followed by four numbers.

Mike, honestly, why call someone a fag because of what kind of car they drive??? And actually I prefer JDM's company to yours ANY DAY!!!
He's a sensible human being and you aren't. And who cares what he drives, without even seeing each of your cars I would put money on his beating yours because for some reason, I'd be willing to bet that your one of these guys with a 2.2L Cavalier with an intake, a muffler, and 346 lbs of stickers.
Just shut up man. I know I just stereotyped but I'm probably right!

I wouldn't. They've become the third least reliable cars made. C'mon, window regulators fail and the window falls into the door.
He's a sensible human being and you aren't.
What can I say, everybody loves me.

Keep in mind I drive a 125bhp 2.0 that is missing due to a fouled plug.

Ditto.
