Thread: codes codes codes gotta love them!

So I was on my way home from some where last night and got on my car a little bit to let her breathe as some might say haha, and the check engine light came on. I went to the car store a little while ago and had the check engine light read to see what my car wanted to tell me oh so bad. These are the codes it threw at me: P0102 (MAF) - P0122 (TPS) - P0300 (Random Misfire)- P1404 (EGR). Now my question is, can one of those codes cause all the others to pop up and so on? I was reading online that the misfire may be caused by the faulty EGR valve, is this true? I need to some what figure all this out by tomorrow night because I am driving about 3.5hrs to Cape Cod for two job interviews, need to make it cause I am jobless right now haha. But any ways, any insight what so ever on this issue or where I should start would be great. Thanks guys!!!

will that fix my issue or at lest help? now that i think of it, i had started my car the other day and was looking at something under the hood and my sweatshirt that i had on got stuck on a plug wire and pulled it off the coil pack, that could be why the random misfire code came up, also my dad had unplugged my TPS for some reason like a week or so ago maybe sooner. So I can probably cross those two off the list, but I am going to clean them any ways and replace the plugs and wires.

haha yeah thats true. i hope it will help, i really need my car for tuesday for those two interviews. not beating on my car for a while, just dont take too kindly to civics passing me at 95-100, specially that retarded looking Si from last night lol.

haha. it was nice passing him doing about 110 maybe 120 i dunno lol. then my car stalled and i just looked like a moron . **** happens tho. not gonna beat on it till i mod it a bit. ill try and get back on here once i get all of that done to let you know if cleaning all the sensors n what not. gonna definitely change the plugs and wires tomorrow.

i went and looked at all the sensors to see if any were visably damaged but they werent and i had the car running. while it was running i heard a tsssssss type sound and i tracked it down to a broken vaccume line. i repaired it with some rubber hoses and the issue that i was having seemed to go away. i also noticed that the vaccume line that was broken caused the egr valve to be stuck open. i am not too sure if this fixed all my issues tho. i took the car out for a ride to test it and see if the acceleration hesitation was gone and it seems to slightly be a bit better but after i hit 50mph at wide open throttle it seems to be slightly hesitant. now could this be caused by the maf sensor being bad or the tps being bad?

i didnt even think of that when i was at the car store earlier. i bought maf sensor cleaner and cleaned the sensor so maybe tomorrow when i go out for the day it will be fine.

Bill?

it was an older Si with just a short ram intake, i know the kid he is from my town. but any ways, i thought i had fixed the issue with the melted vaccume line but i was way off with that. i decided to do a complete tune up and when i pulled out my first spark plug, the electrode was GONE MELTED MISSING! i was so besides myself when i found this. to make a long story short every other plug was the same exact way, how my car ran from sat night till monday no effin idea. if i could figure out how to post some pictures on here of the plugs i would do so.
