2007 - Weird Idle / Random Dies Driving
 

Hi!
I was hoping to get some assistance with our 2007 Aspen 4.7 Flex(I do not run Flex gas). It has about 77k miles on it, mostly used in FL. Now it is located in IL and we are starting to have a few weird issues. It started to idle funny, right at 600 RPM then jump to 1200 then fall to like 400. Sometimes it'll turn off but not usually. I already swapped out the Idle Control valve(that didn't fix the issue). I was coming home from work the other day, super short 5 mile drive. I was coming down a back road and the Aspen just died. I turned it off, let it sit for a few minutes, started back up. The engine light is on now, throwing code P2074, Manifold Absolute Pressure/Mass Air Flow -- Throttle Position Correlation at Higher Load. I did install a new filter also checked to make sure nothing blocking the air path. I am confused at my next move, do I swap out the TPS(Throttle Position Sensor) or MAP(Manifold Pressure Sensor)? Or am I in the wrong ball park and should be doing something else..

Probably needs a new TPS.

MOPAR5017479AA

or STANDARD MOTOR PRODUCTSTH190

But you might as well do the MAP as well. MOPAR 56041018AD

Thanks. I'll order them and swap them out..

So my battery was leaking a little bit and I swapped it out.. That seems to have fixed it, which is odd.. Now to figure out why it takes 20 minutes to get to temperature

Not odd at all, a weak or failing battery will cause a low voltage condition. It is well known that Chryslers do not tolerate low voltage which causes all sorts of random weirdness.

Well the issue is back.... I have NOT replaced the TPS yet but I did throw the code today, P0068 -- Which apparently is MAP/MAF Throttle Position Correlation. Do I replace the TPS first or do I something different?
