I swear to god It'll blow up again

[KlipzSpyderGST]

Alright guys, as I am sure you have figured out, my car isn't running exactly as it should. The car actually has been down for about 2 months due to a spun bearing. Through a warranty on the car, I recieved another 7 bolt with 40k miles. I know I should have gone 6 Bolt, but I really had no choice in this matter.

Now, the new motor is in. But It still definitly has some few bugs, and was hoping some of you could help me out. At WOT, the car bucks, almost like its pulling fuel, or I might be misfiring. It also seems to be getting pretty bad gas mileage, or at least seems to be. I also believe it to have a possible major boost leak, I swear I can almost hear it. But I don't think a boost leak could cause the car to buck and almost die?

That's another thing, occasionally if I do hit boost, which isn't what it should be, after I come off boost it may die. It's done it a few times now.

If anyone has any ideas, please help!

I plan on putting in new plugs for sure, and I am going to look around for leaks. A friend also suggested maybe I have a bad Fuel Pressure Regulator?


Any help would be appreciated!

Definately do a boost leak check for sure. Plugs and wires will help the car bucking at WOT. I'm not sure it could be the FPR, maybe a fuel filter.
Do you have any CEL's? Maybe a bad o2 sensor would cause bad gas milage.

Do I have an A/F?....Gauge?...Wideband?

And yes the CEL is on.

Last night after driving it around some and occasionally popping the hood, I noticed almost a whistle from the TB. I put roughly 20 dollars worth of gas in on Wednesday, and I am just a hair above E now, and according to my tripometer, I've gone roughly 90 miles. Just thought I'd throw that out to see if it helps.

have you checked for boost leaks yet or are you just not going to?

Oh yeah, I posted that before I got ready and now I am going to be out in the garage looking around.

hey it might be a gas leak check and see if you have any by throwing baby powder around the hoses and fittings to see if you're leaking gas.good luck.
