when it flashes its mostlikely a misfire, which is obvious, scan it see wat cylinder or cylinders are misfireing, then get further in it, might be a coil pack or fuel injecter, if u did plugs and wires already

Ok i def changed the wires tonight, and still nothing changed, it was knocking and being all weird.. and yes i have to drive my car to work so when the light starts flashing i turn off th ecar wait ten sec and go, when the car starts heating up the problem isnt as bad but still there. So could it be the cats? or what? is it expensive? thank you all for replying and having input! :-)

Seriously, if you just did a plug+wire change, check to make sure one of your wires didn't shift and is now resting on one of your header pipes (had it happen once before)

naw what i mean is the there is a possibility that since there is a misfire and the mixture is not being ignited completly the gas can clog the cats! why else would the computer want you to turn the engine off immidiatly! thats how my cats got clogged! i just finelly removed my y pipe yesterday, there is some broken peices in my cat

Ha ha.
On a serious note, may I ask why you (the original poster) didn't just bring the car to Autozone and have them scan it for free to find out what SES code is actually being thrown at you? Why the EFF would you (original poster again) rather just start buying parts and taking time to diagnose it yourself????

sounds like scanning it is the easiest way to determine why the lights blinking in the first place...kinda why its there! anyways id do that first and go from there...simple as that

You can buy a code reader for about the price of 2 tanks of gas, or less. Doesn't have to be a fancy one. I consider it an essential tool to have. Ever since I took one of my cars to the shop for a SES light only to find out the gas cap was loose. A code reader won't always tell you the exact problem, but it will point you in the right direction. And there is an OBD II data port on every car since the early nineties. OBD=On Board Diagnostics. The port is right under the dash, above your right leg, on the drivers side.
