P1684 - P1299
was on the highway when i noticed the engin was reved up on its own without stepping on the gas. so my reaction was to control it by tapping on the break.. soon as i slowed down the check engin light came on and the engin started to loop really bad. I can tell the bad loops are compliments of the ecu keeping it from reving to high. i ran the key dance for codes and got P1684 P1299 anyone experienced this?

Could be a vacuum situation. Check hoses and PCV. You also might wanna check the related sensors for proper operation (IAC, TPS, MAP etc).

hey man,
your 1684 code is just a status and is not an indication of a problem. 1684 just means that the battery has been disconnected with in the last 50 ignition cycles. I dont think it ever goes away. I still have it and i have a scan tool to erase codes... probably a tricky way to get DCX to get us back in to the dealerships
1299 is a different story... 1299 indicates a large vacuum leak. to be specific it is saying:
P1299 - VACUUM LEAK FOUND (IAC FULLY SEATED)
WHEN MONITORED
With the engine running.
SET CONDITION
The MAP sensor signal does not correlate to the TPS signal.
POSSIBLE CAUSES
* Vacuum leak
* MAP sensor defective (out of calibration)
* TPS defective (voltage > 1.5 volts at rest)
* TPS defective (voltage < 3.4 volts at wide open throttle)
which explains your bouncy idle... if you cant find the leak... take some Throttle body cleaner and spray it around the spot you think the leak may be coming from. if you spray it and you hear the engine rev up then thats where your leak is...
Good luck

I'm pretty sure it isn't your hot air intake man. A short ram wouldn't do that. It's just a little extension from the TB to the filter.

glad to hear you got it fixed. The bellows tube is notorious for coming loose.

Try this, remove pos battery cable and fuel pump relay for a 5-10 minutes... then return them, and cycle the key and try to pull codes, should be gone.

wont hurt anything if the codes are still in the computer... why's it matter? drive for a few weeks and it will wipe the codes, so long as you dont have the error again.. after a certain amount of successful trips, the code will get wiped.. if it doesn't, just pull the power terminal off, go have a beer, come back and re-attach... consume a second immediatly after, as a reward to your hard work lol

Ive had the codes pop up and go away by them selfs after 3 days without unpluging the bat. its been more than 30 cycles and about 3 days so far and it always pops up. only reason for concern is i have a fix it tecket for mod intake and need to pass a full hour inspection with a state official reffery and so far i already failed 1 inspection for not having the stock air box lid and stock air filter. this reffery is anal about everything, he can fail me for not haveing the right oil level so i just dont want to deal with this guy anymore.. so if my map or tps sensores are bad then i need to get them fixed so i can pass the smog inspection..
ill try to reset the ecu by dissconnecting the bat.. ill keep you guys posted.

You turn your car on 10 times a day! wowzers youre a busy guy!
A failed TPS and/or MAP sensor would give you much more trouble than just a code. The car would run horribly. If youre rev situation is resolved, the code will eventually make its way out of the computer. D/C'ing the battery is a good way to go to speed things up, depending on what type of code it was. If it comes back after doing that, post back up. Also, be sure to disconnect the NEGATIVE terminal, not the pos as suggested above.

i live in california. south cali..
basically the guy is giveing me a smog test that i have to pay and if i fail he wont do the repairs. i have to take it to some other shop get the reapairs done then run a smog at that shop to make sure i pass before i take it back to the state reff and pay him again after 1 week of schedualed apointment. then manditorily appear in court say im guilty and pay a fine of $345... all becouse i didnt have a C.A.R.B sticker and stock filter on the intake.
oh and I d/c the bat and the code went away. its been off for about a day now so im happy..
and the 10 cycles was only for testing. i thought the code would go away after 3 cycles.
