Okay I just registered here today, as I do with any vehicle I purchase or own. I join the forums and share my knowledge and gain knowledge as well.
Anyways, bought a 2002 Sonata 2.4 with 135k, power windows all working, sun roof working, lights working, no burn marks (was a smokers car though) a few dents and scratches (Il be posting pics of the car here shortly).
The owner said he ran the car low on gas til there was none left and had to replace the fuel filter, this was two days before i was scheduled to purchase it. He replaced the filter and called me saying the car was not idling in gear ( it was previously not idling in park or neutral before the filter install ), then he calls back saying he got it working.
Shows up, cars running like a champ, quiet as ****, everything worked great. I pay him, end of deal.
First day I decided to install a after market stereo so I could have an Aux port. After blowing a couple fuses by accident ( cluster, ecu, radio, clock) I replaced them all with fresh ones and finished the install.
Now comes the problem...
I went to start the car up and it wouldn't start, so after maybe 4 attempts i gave it gas and it started. The idle went down so it wasn't holding it at 800 rpm or whatever it is.. i figured **** i forgot to reset the ecu so maybe the air fuel mixture is way off. My scion tc would turn off if you didn't let it idle for 15 minutes after resetting the ecu... soo I pop the hood, to my amazement the MAF sensor is disconnected...
I checked under the hood prior to buying the car and didnt notice this, dont know why!.. so i pop it back in, disconnect the battery neg for 5 min, press brake pedal, reconnect negative and go to start but it wont even hold idle. it turns off every time.
NOW it said on some Hyundai post to get in and immediately drive the car, i can do this and when i do it and then park the car idles fine and if you turn it off, it cranks back up with ease and runs perfect . but i have yet to drive it for 30 minutes as it said to do... maybe only 5-10 but still shouldn't that be enough for the ecu to learn the air to fuel ratio or is this another problem?
maybe the maf is dirty? haven't been able to check cause i don't have the torx bit.
Any input from you guys is GREATLY appreciated
feel free to ask any questions
