Hi Everyone,

I new here please be easy on me. My car runs rough and stalls a lower RPMs and if its cold out it starts hard. I accidently blow the A/C fuse when I was working on something else and the car ran realy good then including gaining about 50 miles on a tank of gas. replaced the fuse and milage droped back down and car ran bad again. Today we hit 90 here and needed to have A/C.

I checked the codes had a bunch

P012 History
P013 History
P030 History
P039 History
P040 Current
P052 History
I039 Current
I052 History
I cleared all codes and drove about 5 miles and the only one to return was I039

Thank you for your time and expert wisdom
George

 

Welcome George, well the majority of the codes you posted are ignition & emissions. Except the 52 code which is anidle speed control. The 039 code is ignition misfire. So you probably have an electrical demon roaming around at the moment.

 

Hi Big five double zero,

Thank you for your help, The only eletrical thingy that I notice is my rader detector goes off at will, I thinking its picking up noise(feedback) from something but cannot figure from what. everytime something with a big electrical load happens it goes off such as the trunk pull down motor or a big accelation on the gas.
