Engine light code
Hi Everyone
Recently I got engine light on, the car started shaking when idle and hard to accelerate sometime. I took it to the deal to check it out, it has code P0171 P0174 P0300 and P1170. At this time they mention that is the port fuel injectors issue, I need to clean the injectors, therefore I spend a few hundred bucks on cleaning that, but it’s not working at all, codes are still here. So they recommend to change all 6 port injectors, that will cost more on me.
so far for my understanding P0171 bank 1 too lean and P0174 bank 2 too lean is for air leaking? Replaced MAF sensor, doesn’t work.
P0300 is random cylinder misfire, I have replaced spark plugs and coils before.
P1170 is fuel system and port injection issues.
Anyone will have solutions for that?
thanks!
