I am getting misfires in all 4 cylinders. What could be some contributing factors i know i am running really rich due to bigger injectors and need to tune that out but what are other things i should be looking at. Im gonna change spark plugs tomorrow and hopefully that clears it all up.

 

Definitely time to get some engine management or at least something to tune it

I think some will show you the air to fuel ratios and such.

I could be wrong but if your putting in bigger injectors why not a bigger turbo to boost that air ratio? With proper management i'm sure some good results will happen.

Along those line a slightly less restrictive downpipe and catback could be a definite power gain with the other mods.

Thats all thats crossing my mind at this hour so far.

 

got tbe, vf22, utec, and wb02 sensor. All the nessacary things to tune the car but was wondering what things i should be looking at to get rid of the misfires. Thanks
