Hi,

I just done the !wire mod and also installed a 500w amp and sub.
When driving it today the ses light was flashing for a while, then went off, then flashed a bit more, then went off, etc etc.
My ses light has been 'on' for a couple of years now, I've had it checked, and it was diagnosed as a manifold defect, and a slight problem with the AC. It was cleared at the time, but came back on soon after.
I will be getting it checked out asap after christmas, but read another post where a flashing ses is a indication of a catastrophic misfire.
The idle did seem a bit rough at times.
Any idea what this might be (guessing it's !wire mod or sub related), and is it safe to drive like this?
I got a drive of a couple of hours christmas eve in it, will it be okay?
Thanks for the help,
Paul.

if it is flashing that means that the car is missing- could be fouled plugs or wires. Take a look at all of them before you pay someone to look at the car.

Also you can go to autozone and have them check them for free. just write down the codes then type them in google and you get what the codes are.

Okay, great thanks, that narrows it down alot.
I just run it again, and the light stays on.
I will check plugs and wires asap, and get the codes read.

Thanks for the help, and if anyone has more to add, please do.

I had this problem and it turned out to be a busted piston. Never could figure out the prob. until we did the compression check. I have hptuners so i could track the misfire in each cyl.. I kept getting the misfire like crazy on #5 so i swapped an injector first from another cyl, misfire still stayed @ #5, then changed the coil pack to a diff cyl, then the plug wire, then the plug each time seeing if the misfire moved to a diff cyl. which it didn't. at this point it was either gonna be a broken valve spring, rings or something mechanically wrong. Did a compression check and sure enough #5 was only holding 30psi i believe, supposed to be in the 175psi range i think can't remember....
Just do yourself a favor and stay away from a dealership because they will rip you a new one, and morethan likely still not know what the problem is. If you can do what i did and make sure it isn't something simple like a clogged inj. or bad coil pack than do those things first. Next get your compression check and/or a leakdown test done to rule out mechanical failure.

Thanks for the pointer 273sunsetZ.

I'll swap the plugs and wires first, and see if that solves it.
If not, I know where to start looking first.

No problem, hope its something simple and you get it taken care of. Also keep an eye out for the car smoking, my SES light flashed for a few months on and off before it started smoking and thats basically when that cyl. shut down.

I hope it's nothing as involed as that.
I'm in the process of buying new MSD, NGK Spark Plugs & Wires.
Hope to do !AIR soon to, so that should help with the install. Never done the plugs on one of these before, should be fun!
Thanks for the advise.

i had a flashing ses light and the problem was due to the spark plug. it read random misfire for the code

haha... have fun with that. I've gotten used to it cause i change the plugs more often since i'm on the bottle, but the first time i did it, payed a shop 40 bucks to put the last 2 in on the passenger side....
