i am trying to diagnose an issue. today, on the way to school, my throttle was acting a litte stiff, and my car was slightly bogged down. about 3 minutes later, my check engine light came on.

i have not gotten the code read yet, as i need to get to work. i looked under the hood, and there is no smoke, fluids, or gasoline smells.

my guess then is a leaking fuel line, which happened in my old car, under similar circumstances. tomarrow, i take it to autozome to get it diagnosed, and if i am right, ok.

my question is, does anybody else know what it could be? i will know for sure if it is a fuel issue by tonight, when i can see what kind of miliage i am getting.

if it is something that simple, i wont have to waste a day taking it in to a mechanic. HELP!!

thanks again to whomever can offer input!

if you have a check engine light (CEL) then pull the code yourself by doing this (I am assuming you do not knwo this, so...)

stick key in ignition, turn like so: on, off, on, off, on and hold there, look in the milage display and you should see a P-code, and then compare to this...http://forum.2gn.org/viewtopic.php?t=11307
it will get you started to find out what step to take next.

Also, check your gas cap and make sure it is tight.

Thanks for that information, it's great to know that kind of stuff!

i tried the ignition thing, and never saw that p-code. tried the ignition all the way to on, off, on, off, on......and nothing happened. i got my trip odo to saw 88888.8, but no p-code. then the check engine light turned off, but i didnt do anything.

what the hell??????

on, and then back 1 click. Don't pull the key all the way back to the removing position or all the way forward to the start position.

i did that, but i will try again.


AAHH. GOT IT!! p-0068, something about intake manifold and throttle correlation.

i installed my new mpx throttle body last , but no cel until today. why??

OOOOOOOOO - this helps some, I believe that the 03 has issues with a 60mm TB... isnt this the same code all the 03 users get???? I think there is a thread about it somewhere...

that is an awesome trick to find that stuff out with... gotta remember that the next time

yikes that might not be the best place to get a car diagnosed.

haha sorry I had to

is it an R/T...i thought the 03+ R/T was the only one that had the problem. I have the MPx one on my 04 and it runs great

Im guessing this is happening because there are no maps in the NGC computer to deal with that much extra air.

rumor has it i am SOL
