These were ma last reading but i for get the codes for the bank 1 02 1 and 2 i will connect it once i get back to the device its not on me at this moment p0300 misfire...p0200 injector control circuit.... p0171 input speed sensor circut low input..... p0174 lean bank 2... c0227 left front wheel speed signal erratic..... c0225 left front wheel speed sensor open ....c0281 brake switch circut... c0291 lost communication with bcm
Also check engine light will blink when acceleration which with ma understanding is the 02 sensors cause random misfire ? Also some of the sp had oil resadue one was wet from gas i do believe that one was b1 3rd back sp 5 maybe and seems that fuel injector wiring clip is loose not sure if that would cause all this i check it with each shut off
Stupid question just herd it may be flexfuel how do i know this ..
