Teddy Posted June 4, 2006 Report Share Posted June 4, 2006 its a good possibility, but it must of been a desent sized rock :monkey: Quote Link to comment Share on other sites More sharing options...
Medicine_Man Posted June 4, 2006 Report Share Posted June 4, 2006 is it a MAP-sensed 4AGZE or AFM 4AGZE? Check all the vacuum hoses etc, make sure the manifolds are tight.  Check it over for fuel leaks, make sure the ignition timing is spot on.  Get someone to check all the fault codes on the ECU as well. If something isnt right, it should throw a code  Good luck!  I have deleted your other topic as it is exactly the same.. Quote Link to comment Share on other sites More sharing options...
Biggo Posted June 5, 2006 Report Share Posted June 5, 2006 O2 sensor makes pretty much sfa difference to a 4agze's mixture (ok maybe a lil richer). Â First thing you could do is get a tune, least the c**ts who do it will find the problem for ya :monkey: Quote Link to comment Share on other sites More sharing options...
