[QUOTE="Davisenvy, post: 17007880, member: 204917"] The pumps start running as soon as the key on, but engine not running. Fuel pressure is at 40 psi with the key on and at 30 psi when the engine is running( by the gauge under the hood). I'll have to go out tomorrow and check the fuel lines and filter. I do not see the FPDM in the back drivers side of the trunk. When I say the car is running like crap, I mean it is hard to start when its cold. I have to feather the throttle like an old carb engine for the first 30 sec or so to keep it running. If it does stall, when I restart it tons of smoke comes out. Second, the drivability is terrible. The throttle on/off feels like a switch. If I'm in traffic in the first 3 gears the car will buck if I try to just maintain a speed and driving through my neighborhood is impossible to keep from bucking without using the clutch at any rpm. Third, I have idle surge. It usually doesn't start until the car is warmed up and mostly happens when I come to a stop. Fourth, at WOT my car looks like I'm rolling coal. I know fuel is added, but it looks like a diesel truck. Fifth, stumble at idle. Might be part of the surge problem. The shop has had the car a second time and their second attempt at the car has lessened the above problems by maybe %25, but they are far from fixed. I feel like there is a mechanical problem (tps, vacuum leak, fuel line) that they are trying to tune around. They also unhooked my Steeda oil catch can because it was causing the car to surge. I saw it bypassed when I got home. When I hooked it back up, the surge did worsen, but when unhooked it lessens the surge, but doesn't fix it. My car ran like a top with the BAP, and VMP tune. Something is wrong and it's making me sick. [/QUOTE]
