Gettin:

p0352 coil malfunction primary and secondary circuits

p0171 system lean bank 1

and a misfire on jug 3 (can't remember actual code, too lazy to go look)

Im hesitant to change the coil just yet... where would you guys start? Which bank is jug 3? could a ****ty injector cause that lean? ARRRHHHGHHH

oh also, i checked fuel pressure a while back and got a 28psi "ish" reading, Chilton says 35-45 psi
