the car leans out while having stable inj mS and ign timining according to haltech, and the afr are pretty linear say 13.5 on part throttle and then all of a sudden once in a while i will go very lean like 20:1 afr, i was quick to blame the injectors, but i swapped the primaries for a diffrent set, since those are the only ones working under light load, but that didnt do anything still leans out. anyone else have this problem? i am thinking the haltech might be fried. i doubt its the wiring also.

bad sensor from what?
i checked the fuel pressure and that was 42 psi, so i am puzzled at the moment what else it could be

its not that it runs lean, it SPIKES lean once in a while while cruising, and then on WOT it will pretty much do it all the time. i am gonna look at the coils maybes somethign is shorting out?

its not the tps, the datalogs are very smooths, everythign is stable.
the only thing i can think of is either some wire for injectors is loose somwhere on teh haltech harness or the ignition just fires whenever it feels like and causes this to happen.
