The other day dad and I when for a drive right, So he turned the a/c on like couple minuets after start up. We Backing out and the car dies! Check engine light came on and everything. I dont know what that was but this is the first time it happend. It was fine after that, could this be a problem thats not a big problem yet?
Strange thing happend
- Thread starter 89Joe
- Start date
hahaDAMN THAT WAS AWSOME!!! Ok here are the codes I got, it's ither 14 or 41. Im pretty sure it's 41 because the throttle position senser was replaced by another one which would explain the stall out when the a/c turned on and the strange jumping of the throttle. I have no idea what the heck 14 means so tell me your oppinions on the situation. Could it possibly be both?
take ypur time, if you're throwing two codes (or more), it will tell you. Sounds like it's your TPS. It's a bitch to get correct, but it's important to get correct.
41 Throttle Position Sensor Signal Diagnosis
Open or short circuit in throttle position sensor signal.
Trouble Area
Throttle position sensor circuit

thats it right there made sure and whent back :biglaugh:

I had the same some time ago.
It's most probably your TPS.
You can ajust it by loosening the 2 screws of the TPS.
Then you have to disconnect the connector, and use a multimeter to measure the resistances, while keeping a .5mm feeler gauge behind the dashpod.
The TSRM tells you exactly what values they should be.

Be carefull when ajusting. Sometimes ajusting a tenth of a millimeter does the trick already.
Good luck.

Could this explain why the car seems to jump? This happens ever so often but when it dose you know when. Also could this be an electrical problem? Maybe something with the ECU? I have a spare maybe see if that dose the trick? Then about what you said Thevork, what exactly would this do? is it a way to adjust the TPS in effort to fix the idle in some way? :icon_conf
ECU's rarely ever go bad. i've only EVER heard of one. it's not your ECU doing it. yes, thevork has the right idea. the TPS can cause all kinds of idling problems, as well as stalling problems etc... the list goes on. fix it per the tsrm in the link both i and thevork gave you, and you'll be happy.
if you cant get the specs on it correct, then get a new TPS and adjust it with the throttlebody off the car. (much easier) when it's fixed your problem will vanish.

Also, after setting the TPS correctly please check your timing.
Because if the timing got set ever with a bad TPS or TPS setting then most probably the timing was set with the A/C on.
