hello, my car died on me one time when i made a stop. is having a check engine light so check it with the code reader. at first yesterday i spend the day trying to diagnose what was wrong with it. at first it have p0135, p0300, p0301 codes; so i went and check for solutions to this codes. after a while i erase the code drive around the corner and it came up with the check engine light again, so i connect the scan tool and for some reason i was not having the p0135 code any more, but then i had two new ones p0449 and p0443. including the p0300 and p0301. do you think that they are on a relation with the misfire ones i mean can this evap problem cause the engine to misfire? and i also experience a rare situation. i turn the car off and then turn it; in less the a minute the fuel and temp gauges went al away down and the theft system, abs, seat belt, check oil, lights came on, and my wipers and electric windows, radio, and a/c stop working. a couple of second after that a the lights went off, and the electric windows, wipers, a/c, radio and gauges started to work. when that happen i could hear a difference on the engine speed. and the engine fills like when you take a spark wire when the engine is running. what could be wrong.i erase the codes and wait a little i went fore a ride and check engine light came on and now the only codes that is reading are p1122, p0449, p0300 confirmed codes and p0443 and possible code. after a while i notice that the rpms goes up and down between 500 rpm and 1200 rpm if i push the gas the and then take the foot off the gas it will stay in 1200 rpm for 5 seconds and up and down like i told you. and also the car is not going more than 4000 rpm.
