SES Light

[rednightrain]

My car is a hair under 55,000 miles. And all the sudden today, my car started running real rough and the Service Engine Soon light came on while driving to work. I also noticed that when ever I would accelerate it wouldn't respond like normal(a real lag as it it was towing a boat) and the light would blink, the rest of the time it would just stay on.

I live in central NY and it was pretty cold this morning, blowing snow and all, and my car wasn't driven for 2 consecutive days. I also filled up my gas tank (from E) on Friday. These may be factors in why it ran like *** .

But I'm thinking it may be 1) Bad Gas
or
2) Faulty Spark plug(s)

What do you guys think?

Thanks

2) Faulty spark plug or how about my option 3

Faulty Wires.

I would get an AutoTap to try and diagnose the SES light so you can find out which cylinder is misfiring. A flashing SES light almost ALWAYS means misfire.

Yeah, go to autozone and have them read the code for you. They do it for free. Blinking light always means misfire.

Youre close to 60K miles, its probably your wires...I think GM will replace them for free under like 70K miles because the original ones were found to be craptastic.

So get it read for free...go to GM and tell them whats up, they will read it and put new wires on for you...then get new plugs.

I wish my car would misfire so I can get new wires...but with 63K miles it still hasnt had one.

When mine did that at about 70K miles it was a coil pack. If it's not the plug or wire, it is probably that.

Happened to me before. Turned out to be a faulty spark plug wire. My guess its the same for you.

[rednightrain]

So what plugs and wires would you advise? And how much do you think they'll cost me?

well a good set of wires are the Taylor Spiro Pro.. you can get them from
http://www.thunderracing.com for like 50 bucks.. btw thunder racing also happens to be a sponsor of the board.. :D

plugs.. I like the stock ac delco platinums, though they are quite pricey.. we also have some pretty loyal NGK fans on the board to..

NOOOOOO!!! I WISH! :mad: :mad: :mad:

I already tried that route.

Evan (Only4U) got free wires from GM. This was on a 1997 Camaro though...

yes that year and stuff had the recall for it. It's a defect for all 93-02 F-bodies, but GM "supposedly" fixed this in 98 I believe. Bast*rds wouldn't release me the car unless I paid them $400 for the F*&) Plug Wires and the faulty coil pack I had. :mad: :mad:
