FD Running Issues
(I sent this to the fc tuning group on yahoo but, I figured the more eyes, the better.)
Where to begin.. I have several issues with my car, but I will try to stick to the few that are important. My car ran... 8 months ago. With a V-mount and the stock hood, the hot Okinawa spring/early summer was causing all kinds of problems; especially with stock ignition on a street port and 35r turbo (the car has been street tuned by a local shop). So, I stopped driving it. Fast forward to today. I relocated the coils and installed an HKS Twin Power. When I installed this motor, I didn't have new gaskets so I only used silicone (for most stuff). Well, I had water leaking issues so.. I replaced every gasket from the lower intake mani to the water pump, and everything in between. I also installed a GM 3-bar. Before the car would start no problem, it just ran like crap when it got hot. Now, the car will start but it will die immediately. If I give it lots of gas, the car will run and sound great past appx 4000 rpms. But, if I let off the throttle a little, it falls on its face.
There shouldn't be a vacuum leak; all vacuum lines are hooked up correctly etc etc. Now, my PFC map is not setup for a 3-bar. That will change in the morning but, could that be the reason my car won't idle? Could it be a bad gas issue? I am getting the correct pressure at the FPR, plugs are new, getting spark (checked) and air.
Any ideas?
Mods -- street ported motor (local guy), walbro, 550 primary, 1680 secondary, Greddy front mount (mounted as a v-mount), gt35r .82 hotside, 44mm Tial wastegate, custom 3 inch downpipe, Borla 3 inch custom midpipe, RB dual's muffler. FJO injector driver.... I think that should be everything that is relevant.
Thanks in advance. Any help getting my car back on the road would be greatly appreciated. It has been too long. Driving my wrx is getting boring.
