giantrobot9000 Posted July 2, 2007 Report Share Posted July 2, 2007 I just plugged into A2 to get my engine codes,and boy do I have a few (this is a 94 850 Turbo)-443 (cat efficiency low)435 (slow front 02 sensor)231 (long term fuel trim @limits at part throttle)414 (boost press. reg too high)121 (missing or faulty MAF signal)The car is totally stock.Anything there I should be concerned with?

Mesoam Posted July 2, 2007 Report Share Posted July 2, 2007 with all those codes its best to just clear and see what comes backsounds like you have quite a few things wrong thoughthe maf could be the connection (the actual electrical connector)front 02 could be dead and causing your CAT codeboost issue could be vac lines or a waste gate problem or BCS problemthis is why its best to clear and recheck Link to comment Share on other sites More sharing options...
giantrobot9000 Posted July 2, 2007 Author Report Share Posted July 2, 2007 Ok,I started over and it gave me the same codes as well as 2 more!433 (rear knock sensor)425 (rear o2 sensor control)I also got 424....which isn't even listed as anything...?When I tried to reset,it just started with codes again.....I can't get 1-1-1.

giantrobot9000 Posted July 7, 2007 Author Report Share Posted July 7, 2007 Would any of those tie into having a clogged PCV system (which I do)? My spark plugs have also gotten oil on them from this. Link to comment Share on other sites More sharing options...
