2014 Camaro L99 Automatic Eforce, misfire cylinder 7 and 4
hi guys,
we installed a brand new eforce p/n 1562 into 2014 Camaro.
installation was plain with no issues.
but has soon as you drive the car a little bit there is misfire on cylinder 7 and 4
I suppose the problem is on 7 and 4 is only following
already checked wiring for pinching all ok
already checked spark plug (gapped to 0.35) all ok
already swapped spark plug wire ok
sprayed carb cleaner all ok
I removed spark plug and 7 one is very dark with deposit, 4 is ok like others
spark plug are OEM ACdelco
SCT tuner is alredy update to last sw
any good idea for us?
any tip?
thank you so much!
best regards
misfire fixed but poor power gain
hi guys,
we found the misfire issue and fix it out.
the guy who did the conversion put some RTV on the DOD valley plate to help on leak...
I say to him to put it to prevent leak but only on the outer seal.
he put it on all the orange OEM seals, doing so he plugged a bit the lifter oil gallery and the bleed hole you need to create on the gasket does not work.
so... using the car the oil on the DOD lifter keep them a little bit under pressure leaving the valves a little bit open, this is the reason of the low compression.
cleaned it, reainstalled and the car is ok, no more misfire.
thank you for all the support found here!
another knowledge gained on the DOD system :)
