Hey guys, just recently got my 02 GT back after t56 swapping when 2nd gear shift fork bent in the tr3650. Car was running good I thought except for I quickly started noticing a little hesitation at cruising speeds and low rpm. However no codes at time.
It's been a few days and a tank of gas (to make sure wasn't bad gas). And now it's pretty consistently breaking up/surging at low rpm and load as well as throwing P0154(no signal bank 2) and P0173 (Bank 2 lean). Mainly noticeable in 5th/6th but sometimes noticeable in lower gears as well.
Going mid-high rpms it does just fine however. I'm hesistant to just think the breaking up is because of the dead 02 sensor however as breaking up would be caused of a misfire no?
Probably going to tear into it Sunday and check plugs and the like but wanted to see what anyone else might think. Btw car was brought to mechanic who put the t56 swap in for me to check if maybe one of the 02 sensors was just loose or unconnected and said everything looked fine.
Mods are:
Kooks LT headers/ Kooks Catted X-Pipe / Spintech mufflers
Accufab 70mm TB
SR performance CoP
Roush CAI (roush stage 2)
Bama tune
Everything but the alternator (SVE black alternator from LMR to replace whining old alt if it matters) was on and ran fine before broke 2nd gear shift fork and sat for 2 months.
