Well, this is embarrasin'. I was about to post how great my truck was doing since it's recent resurrection and... ugh! It's like I jinxed it! So... now, I have read enough of this forum to know that when I start describing symptoms, you will ask me '...what code(s) the truck has given?' as a clue to where the trouble might be. And that is why I'm asking for the 'paper-clip code getting' technique. Now I tried searching archives for this operation, but I must not be asking the right way... So I thought, "If I name this thread 'get codes with paper clip', then the next ya-hoo like myself who wants to learn how to that, and types it in as such, he will find THIS thread... and there will be much joy in the land." So.. while we wait for the step-by-step, easy to follow, coloring book play-by-play for this paper-clip action... I will give you the main symptom... the truck does not idle normal anymore. I started it up Monday like normal, 1 turn of the key to let her know we're goin somewhere... second turn she fires up. But this time, she acts like.. hard time gettin' fuel! stumbling and rolling thru idle like wants to shut off any second. warms up and runs okay.. but push the gas pedal hard and oops... too much (gasp) fuel? hesitates before moving on.. etc. Tuesday the 'check engine soon' light came on for 15 miles or so... got home, idled while I moved a few cars around to make room for her.. and when I hop back in to back her up into place... 'check engine soon' light is off . BUT she still idles poorly. I parked her and am driving my econo-box until I have time to look into this and aproach her with a paper clip and note pad. What are your thoughts?
