Stalling

Any ideas would be greatly appreciated. My vehicle starts, the rpm's rev to around 2500 at initial start up, then quickly drop to 500 or so, it then sputters out and stalls. The check engine light and the ABS lights are on. If I disconnect the MAF sensor it does the same thing, with the exception to stalling, and idle comes back up to about 800 and is much smoother. I changed plugs and coils, the coils were cracked, and plugs were shot. I am leaning toward MAF, and I am going to attempt to clean it and see what happens. I do not have access to pull codes, but I am going to do a fuel pressure test as well. Turbo clogged? Vacuum to the brake booster is good. Any other ideas?
