This is a follow up from my last question about my 1993 Lexus gs300, changed mass air flow sensor, full tune up, throttle body checked the cats, fuel pump & pressure car runs good in park after a few minutes but when giving it gas it shakes & cuts off I've changed every thing even the ecu.

Car runs great in park just can't give it gas hard without it shutting down with the mass air flow pluged in and that's the third one from the store

Check for a clogged air filter. Have it scanned as whenit's unplugged your car operates in open loop. You may have another problem. Also check all your hoses for a hole in any of them
