Vacuum Problem
#1
I used to have 16-18 vacuum at 800 rpms.
now since i got my car back from the shop, i had lumpy idle (400-600 rpms)
i fixed it by bumping the idle up to 900
At 90o rpms vacuum is 16
when the car is cold the rpms settle at 1500 and the vacuum is 16-18 closer to 16
i can't get to 18 anymore. Possible vacuum or is my motor lossing compression.
I boost 9 -13-13.
Mods are
blitz intake
down pipe,midpipe,greddy catback
HKS PFC FCON
manual boost controller
I think i'm running rich, the whole car is running rougher now at idle (shaking abit)
i have break up (stutters)in high rpms for first 10 min after warming up then goes away, oh there a back fire in there with the stuttering.

Damn, there is alot of stuff you need to take off to rplace the FPD. There are numerous things they could have broken, left unplugged. It will be hard to tell if all the hoses and connectors are on coprrectly without taking off the upper intake manifold

Check all your vac lines and especially the boost sensor. they had to take some of the vac lines off to replace the FPD there is something like 7 vac lines that go to the UIM and two elec. connectors. check all those because they had to take UIM off to work on your car. How new is your O2 sensor? If you FPD is replaced then your 02 sensor could be reading differently from the proper amount of fuel being injected now. Sorry of this is too much but those are my Ideas.
