Consistant Misfire

[Silk90]

Misfire on cylinder 4, does not move when plugs or coils are moved, checked compression and it has 150psi, Here are the codes the car spit out after clearing them. Although i already replaced the MAF aswell.

16486 - Mass Air Flow Sensor (G70): Signal too Low
P0102 - 35-00 - -
16688 - Cylinder 4 Misfire Detected
P0304 - 35-00 - Intermittent
17861 - Exhaust Gas Temp Sensor 1 (G235): Open or Short to Plus
P1453 - 35-10 - - - Intermittent

My only other guess would be the wireing to that coild is bad, the wireing to the injector or something like the coil power module, any input would be appreciated, car is my daily driver and has been down almost 2 weeks

is that EGT on the same side as the misfire? if so, that could be your problem

EGT 1 is passenger side i believe although the misfire is on cylinder 4 (drivers side) :-\

I'm looking for a Coil controle module and seeing if that does anything.

k, but best to replace that EGT before you try to fix other things

I get misfires also when i start to hit boost. These are my codes:

17866 - Exhaust Gas Temp Sensor 2 (G236): Short to Ground
P1458 - 35-10 - - - Intermittent
17521 - Oxygen (Lambda) Sensor: B1 S1: Internal Resistance too High
P1113 - 35-10 - - - Intermittent
17965 - Charge Pressure Control: Positive Deviation
P1557 - 35-00 - -


The first two (o2 and egt sensor) comes up all the time and the last code is what puts my car into limp mode and can only run 5 lbs. It goes off if i misfire too much .

problem fixed, Problem was Power output phase, 237$ no continuety for cyl. 4

although i am still throwing a whole heap of other codes still.

I am having some issues like your as well with no codes so I would like to know what and were is the Power Outout Phase

Thanks

looks like you need to replace your EGT and that 02 and looks like maybe a bad n75 valve

That EGT will make other codes appear as well you need to get that one changed to.
