Hi guys,

I just picked up this 01 s2k with 91xxx bout 2 months ago. i drove my car to work last Friday, while i was driving CEL came on. When i got home i did the obd scanner and it's showing p1457. So i went online and did some research and came up with gas cap thing. so i erased the code went for a little drive and cel never came back on but i noticed the car was stuttering a little, So i thought it's nothing serious. The next morning i started my car i got this rough idle and exhaust poopin noise. So i went for a little ride, my car drives like crap looks like the car is losing power and the cel came back on. I got home plug in the obd scanner and came up with this:

P0302 - cylinder 2 misfire detected
P0304 - cylinder 4 misfire detected
P0301 - cylinder 1 misfire detected
P0303 - cylinder 3 misfire detected
P1399

To all the s2k gurus in Mid-A, i need some your help or advice. What do i need to do to fix this problem? I suck @ fixing car, basically only know how to change oil. Also is it safe to drive the car like that? this is the only transport i got have to travel bout 3 miles a day to work.

Any help is greatly appreciated

Will

 

If it was one cylinder I would start with bad coil but all of them?? Have you posted this in Under The Hood, yet?

 

Not yet, i thought i would come here 1st to see if anyone local had ever experience the same problem. well, i just talked to my boy that work @ herson in rockville, he's going to check it out tmr. i'm crossing my fingers for nothing serious. i'll keep u guys posted once i find out what's wrong.

 

I don't say this but i think something fishy happened. It's odd to me that your gas cap was on incorrectly and then you have misfiring problems i hope some a hole in put something in your gas tank.

 

you don't say what? why do you hope someone put something in his gas tank? that's mean.

 

That's not what it was supposed to say, i wrote that from my drips using the talk to text thing... it'd new to me. I don't wish that upon anyone ever... its sounds fishy to me, like its possible it could have happened.



G L. I hope this is not the case.

 

Have you been driving it hard previous to this occurrence?

Just throwing it out there. Could be a MAP issue. Simple fix, common problem that causes a lot of weird issues. Start with the free fixes before you waste $ and time.

There is an entire thread about misfires in UTH. Basically, there are a ton of different things that can lead to the codes you're getting (bad gas is a possibility). I'd have a read, and go from there.

And good luck!

 

with TopGear and Insert Name, as there are a lot of reasons your car can throw those codes.

 

I understand, thanks a lot for the info guys. Hopefully just spark plugs and coilpacks. I have a friend that used to own an s ran in to the same problem, he told me he just replaced coilpacks and spark plugs will do the job.
