hi everyone i got a 91 4x4 that i just installed a new 22re and for some reason i have awhole lot of fuel sitting on my lower half of my intake. injectors are fully rebuilt. i tryed disconecting my cold start injector made no difference. was wondering on the 91-95 trucks what controls the injectors?

has anyone had this issue ?

 

Are you sure that the injector o rings are not leaking. Is the brass washer still on your fuel line.
Those are both possible things to check. Have some one crank it over you you look to see we're fuel is coming from

 

orings and injector grommets...fuel line has 2 copper gaskets...

dry it all up and have someone start it while you inspect for leaks.

be careful...no smoking!!

 

Not out side the intake in side the intake ya I know werid yes allbthe orings are sealed yes have all the brass washers

 

Also about 1/8 throttle there's a spot where it spikes 18:1 afr or the wideband won't even read it it gets so lean but a hair past it or befor its at 14.8 befor and 13.4 after that spot

 

Can the rear o2 sensore be bad telling the ecu the mixer is to lean ?
