SOURCE: 2004 x-type 3.0 v6 152,000 miles showed codes P0171, P0174, P2096, P2098, P0101, P0171 pd, P1000.

check for vacuum leaks or a faulty mass air flow sensor. all the codes have to do with engine too lean(too much air).

OBD2 "check engine lite" shows


Both codes are system too lean bank 1 & bank 2. First place to start is any obvious vacuum leaks. Look for broken,collapsed or missing vacuum lines. Check egr valve & intake manifold also.

My cadillac deville has the following engine codes when hooed up: P0106, P0121, P0171, P0174, P0335, P0340, P0385, P0442, P0506, P0506, P0507, P0601.


click on the below links for code details.
P0106

P0121

P0171

P0174


P0335


P0340

P0385

P0442

P0506

P0507

P0601.

all of the above codes seem to have a common cause, they all list a bad ecm (computer) as being a cause, and the last code P0601 points specifically to a bad computer. sorry for the bad news, hope this helps.
