Car won't hold idle or start sometimes


Recommended Posts

Mine did pretty much the same thing when my M.A.F. went out? It would start, idle would bounce a little, drop down really low(under 1k) then die, I'd start it back up, it'd die and the it wouldn't start. Just a thought

Thanks for the quick response I swapped the maf over and the throttle body sensor over and didn't change. I can start it up sometimes and it will idle at about 1500rpm then when I give it gas it dies on me.

Hmmm... definately sounds like something involving air/fuel to me.... fuel filter clogged up? I know my jeep would do a similar thing at one point too. Fuel pump was old and couldnt keep up.

I've had a bad mechanical experience with mine as well! Burning think.that's only because the dumb @$$ mother f*cker who I bought it from thought it was a race car and beat the living piss out of it:( BUT! Although my mechanical experience hasn't been great... I love driving mine:) but yeah I'd run the codes!

WTF is a throttle body sensor?

 

Its your idle air control valve. The line for it has come off of the air intake tube.

 

I didn't know the name of the sensor so I just called it that, I will look it over a tube that has popped off thanks!

I had a check engine light before but it came up for the knock sensor and o2, and I would rather not pay for a tow to a shop aha

 

 

I'm sure an advanced auto, orileys, or even a dealership will let you rent a scanner with a large enough deposit.. they'll probably ask you to leave your drivers licence too.

 

 

THREAD JACK!(sorry): can someone explain to me the significance of a knock sensor? Mine throws that code too... feel free to pm me. I don't wanna get charged with thread theft lolololol;)

Engine Coolant Temp sensor did this to me like two years ago. Not trying to rez this thread, just hoping to help anyone reading that might have a similar issue finds this useful/

 

I also had this AGAIN about two weeks ago. Turns out that I kinked the hose from my intake duct into my IACV somehow. Car ran... just not great. Stalled after starting quite a few times, other times it would just idle low and go "potato-potato-potato", fighting off a stall before the engine warmed. Unkinked the IACV hose and it now it runs like a dream. :D
