a quick question,can a faulty injector bring up a code 34 .i know the code 34 is for the mas air flow sensor but i know it is not it,I've changed the idle air control,cleaned up the air intake,n anything to do with fuel delivery.besides the engine sounds like there is a injector fouled up, just want to check with u guys first
thx

 

Disconect the wiring harness from the MAF sensor. If the idle smooths out your MAF sensor is defective. I f the idle stays ruff smething else is wrong. Could be an inj.

 

As well as a burnt intake valve.
Mechanical ills, can trigger codes being set.

 

i 've been figuring it would be mechanical,i will be replacing all the injectors anyways n see what will happen. thx

 

If I haven't followed the stock troubleshooting flow chart for code 34 ( Code 34 chart ) I wouldn't say for sure what it is or isn't.

I *knew* my MAF was good before I installed it, code 33 came up after install, surprise, flow chart said my MAF was bad, and the flowchart was right.
