3 days ago, i had an incident with my chip, i took it out cleaned it super good as instructed by geno, and have been driving the car...running great , today i go to the car wash, wsh car, by hand, get in start car and again check engine and rough idle, though not as bad as the first time, so i pull over turn off ignition, and let it sit for about 30 sec or so, re start car, and prob solved, rough at first, then smooths out,drove for 30 min to see if any probs...none...i am confused,just went out started her again, and no probs is this just a fluke that may happen once in a while . i got the idea from the first time it happened, i just disc the neg cable and recon it and prob solved, i truly did clean that s.o.b. terminal very good, so i don't think that is it, i even drove the last 2 days with the under dash out and computer down just in case somthin is up , bolted it up last night cause i thought all is well, also where do you get codes read?
