injector #1 miss fireing

[awdmonster1904]

I was wondering if its a common issue for galant vr4 to miss on injector#1
the reson i ask is because my vr4 is all stock and it started doing that i checked all plugs and sprak plugs all seam fine
1cly# died of detonation the SP was all mashed up but no damege to piston ???

SO could this be an ecu issue?
bad injector ?

TIA

Its rare for a injector to be faulty. Does it misfire all the time? Just under boost what? Do a compression test and see what you get.

i had the problem with my gsx...the injector was bad... i replaced it and its been fine ever since. Yes its rare but it does happen.

I figure it would be my injector since I always run it low on gas the compression was fine untill the perticular cylinder that was miss fireing detonated and went bye bye sprakplug looked smachec

Note: I have no spark issues it's all fuel issues

All the time, or only in boost?

Check the wiring first to make sure you don't have a loose connection. In my personal experience, the car will actually drive on 3 cylinders for awhile (30+ miles) before it throws the injector circuit code if there is a partial connection.

My car only threw the code when an injector became disconnected entirely. If all the wiring looks good, it's probably time to check out the injector itself.
