Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Did you change the air flow meter .??
Did you check the fuel pressure ??
Having all these codes .
What are the short trim readings at idle and at 2500 rpm .
See this quite often and its normally the Airflow meter .which does not have to tyrip a AFM code as it
may be working with in its set parameters.
What are the AFM reading at idle .
Okay this is a dodgy issue as if not diagnosed correctly you could end up throwing parts at this car and still not repair .
I would suggest you find a shop that can do the diagnostics for you , this they would call for an hrs diagnostic time and
would be money well spent .
Or if you have the possibility to try parts from a known working dodge like yours i would first try the MAP .not the MAF sorry misprint .
As the MAP is the biggest culprit for these codes .
This is located right on front of the manifold just behind the alternator .
Will take a photo of one in the morning as have one in the shop at the moment.
Do you have the use of a good scan tool with live data ,
Don't want you to spend money on a MAP with out first testing it .
Do you have a hard starting when cold .
Black smoke out the exhaust .
Rough idle little lack of power.
First start with fuel pressure test as you have codes for lean and rich running engine .
And if you can have a scan tool set up in live data and check the fuel trim this will tell us a lot ..
Okay this does sound like the MAP sensor , if no tool to test go ahead and replace the sensor .
Then get back to me if needed .
Kindest regards Greg
Okay so after replacing the MAP sensor car started to run better .
But now after a days the engine will now not start .
The codes 171,172, 174, 175.are what you now have after clearing all codes after fitting the MAP sensor.
These are all lean and rich codes . also pointing to the MAP sensor , try your old one ans see if she starts .
Any other codes besides the ones you gave me .
Try starting with your foot flat out on the accelerator could be flooding .
Check a local repair shop they will have the tools for this .they have to.
with out they can not work .
A shop today that has no scan tool is like a car with out its keys .ring a local indy shop and ask .
