p0100 problem! jerking and engine cut offs
i was cleaning my battery and when i was reinstalling the positive cable a couple of sparks came off. i didnt think much of it and then started the rx. sound fine at start up and then the rpm dropped quickly and went back up. so i let it warm up a lil more and then pulled out of the drive way. as i was driving down the street it started jerking bad over and over again and then when i let off the gas it died.
autozone is not to far from my house, so i just drove over there with the hazards on and the rx was jerking all the way and died at stops.
i got code p0100
so i went back home and cleaned the maf sensor, but no luck.
now it cant even turn over.
btw i have just changed my spark plugs and a/f sensors.

P0100 is a Mass Air Flow Circuit Malfunction.
As TunedRX300 mentioned there can be a short here or possibly a dead MAF. Other possibility is an ECM, but the fact that you can get it to start up indicates the MAF is likely a goner.

but tonight ima try and reconnect the battery cables.
i swapped the maf sensor and now its not jerking anymore. the only problem now is that it idles around 750-500 rpm and sometimes dies. i think its because when the problems first happened i got frustrated and sprayed carb cleaner in the iacv hole. i didnt really remove anything except for the intake tubes to get to it. did i just mess up the iacv? would i have to completely take it apart to clean it or can i just unplug something?

everytime i reset the ecu its usually the first start up that is good and then when i turn it off and let it set for a few minutes the next start up has low rpms.
is there a way to clean the iacv without removing it. can i just remove all the hoses/plug ins and then spray through the hole?

I would just spray in the hole and also drive your RX around for a few more days to let it get set in the computer. I occasionally get some low idles here and there and never found a reason to operate on the IACV any more than just spraying in the hole.
thanks lexmex. i just got back from driving it around all day and it seems to run fine.
lexmex...how many seconds do you spray in the hole. i read somewhere 15sec, so thats what i did.

That's about right. It should fill up a bit and then when the engine started will come out in a hole nearby on the other side of the throttle body.
