D16Y8 CEL codes issue: P0170, P0171

[ToTo17]

it is odd that you passed your emission test with a CEL on... you are in california assuming santa rosa is the one by me, do they do an ECU dump or a dyno for a 1998 these days? I know i had a 2005 ford f150 in placer county have just an ECU dump, any pending or faulting codes cause the test to fail. looking to help, not be a jerk, sounds like we are narrowing down your issues with every post!!!

Everything you guys are saying are helping me so I have no problems with the comments. Well they fixed the exhaust leak problem and resetted the CEL code and drove it for about another 50 miles or so to make sure all the monitors were ready to smog. Basically, the check engine light was off for a day before it went back on again with the two lean codes and then they went away and came the P0133 code instead.
