I have a 1996 Grand Cherokee that that throws a 171 code "lean"gas code.

I never get any other codes, this usually happens when it's hot. I get a real rough running engine when this happens..after a couple of minutes its smooths out and is fine.

any thoughts?

 

Fuel pump

 

what is the best replacement brand -- whole unity replacement.

I saw a video -- replacement looked messy but doable.

 

An original Mopar pump would be best. Stay away from Airtex, they're junk. Stay away from any pump that was made in China ....if you can, that is.

 

Thanks Bustedback

I have found a couple of different pumps
A real mopar http://www.cherokeeforum.com/f5/1996...71-code-172095

and

sorry -- that was http://www.carid.com/1996-jeep-grand...m-8373717.html

Just a quick follow-up -- used the MOPAR pump and a new filter.

1 week -- no code 171! runs MUCH better, has a real jump when you hit the gas. I think better mileage too -- but didn't have a before / after measurement.


Bustedback -- thanks for the help on this!
