So i parked my car for the winter. I stored it in a barn. disconnected the batt. blah blah blah.
so yesturday i went to get it out. i put the wheels on, connected the battery. started it up first try. no problems. i moved it out side and let her warm up. its in fast idle till it warms up.

Then all of a sudden the rpm's start to go all crazy. 500-1800...up down up down and so on. turn it off, then back on, same thing. give it a couple quick revs. nothing. turn it off and wait. start it up runs fine for 45 seconds.

then all the warning lights on the dash come on. and i mean all of them. looked like a christmas tree. thats when the car stared to act really funny. the rpm just bounced off 1600 mark and kept on doing it, like it was hitting a rev limiter.

can someone give me any help?

 

Gas might be trashed after sitting for that long.
Or a bad sensor, TPS, IAC, or MAP.
Try disconnecting the battery again & reconnect it.

 

id check battery voltage. my wifes 05 mdx had similar problems and it was the battery. the dash looked like a christmas tree so many lights were on

 

thanks for your help, i think it just wanted to be driven. i started driving it and it seems fine. the transmission feels kinda funny. If im light on the throttle it hesitates to shift. if i havve my foot in it, it drives so nice

 

Sounds like a IACV problem to me

 

i plugged my obd2 sensor in and it showed idle control motor, something along those lines. cleared the code and started driving it. idle is fine now.
