well my problem is this. the car starts up and idles decent then once i put it in reverse and back out its stalls and there is a lot of hesitation in the throttle. Checked for any major vacum leaks and found none although the car is only pulling about 12hg on the vacum gauge. any ideas? this is in my b14 with u13 bb motor and 60lb injectors on the jwt 72lb program

should be about 19-21hg. something is deffinatly leaking. unless you have cams from what i've heard.
I dont know much about Injectors... but unless you have some other feul managment your not going to be running the right a/f. But someone else will have to chime in on this for my knowledge is limited on injectors and feul managment.

check for leaks around the injectors. 12-14inhg is only normal with s4 cams.

I am running s3 cams. I am about to do another boost leak check but I'm pretty sure there is no vacum leaks.

I was told an easy way to check for leaks is to spay some carb cleaner around your fittings and injecotrs, and if the idle changes you have a leak. Thats just one way I've been told. But who knows I might try it to see what happens on my car. But I also have a pressure testor too.

ok did another vacum leak check. I am certain that there is no leaks. Could my timing being off cause this sort of problem?

Are you sure your injectors are firmly seated in your intake manifold. The motron 60lb injectors are skinnier than regular injectors, and are none to blow out of the intake manifold. People put 1/2" pvc pipping around the injectors to make sure that they stay seated in the intake manifold.

12 in hg. is way off. I have 17 in. hg with S3 cams. My guess is that if you can't find vacuum leaks, the cam timing is off.
